chore: update LTS tag naming

[fzipi]

what

• update the lts tags so every build has some specific tag

why

• while writing a blogpost, tried to use the base CRS v3.3 lts but there was no tag for it
• trying to get a unique version, other problems surfaced.

e.g. in main

      "tags": [
        "owasp/modsecurity-crs:nginx",
        "ghcr.io/coreruleset/modsecurity-crs:nginx",
        "owasp/modsecurity-crs:4-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4-nginx-202609140609",
        "owasp/modsecurity-crs:4.29-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.29-nginx-202609140609",
        "owasp/modsecurity-crs:4.29.0-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.29.0-nginx-202609140609"
      ],
...
      "tags": [
        "owasp/modsecurity-crs:nginx",
        "ghcr.io/coreruleset/modsecurity-crs:nginx",
        "owasp/modsecurity-crs:3-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:3-nginx-202609140609",
        "owasp/modsecurity-crs:3.3-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:3.3-nginx-202609140609",
        "owasp/modsecurity-crs:3.3.10-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:3.3.10-nginx-202609140609"
      ],
...
      "tags": [
        "owasp/modsecurity-crs:nginx",
        "ghcr.io/coreruleset/modsecurity-crs:nginx",
        "owasp/modsecurity-crs:4-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4-nginx-202609140609",
        "owasp/modsecurity-crs:4.25-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.25-nginx-202609140609",
        "owasp/modsecurity-crs:4.25.1-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.25.1-nginx-202609140609",
        "owasp/modsecurity-crs:4.25-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25-nginx-lts",
        "owasp/modsecurity-crs:4.25.1-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25.1-nginx-lts"
      ],

We were adding the tag owasp/modsecurity-crs:nginx to the v3.3, but also in the v4 lts, and the default "latest". This was wrong.

Now this PR changes that to use an "lts" versioned approach:

      "tags": [
        "owasp/modsecurity-crs:nginx",
        "ghcr.io/coreruleset/modsecurity-crs:nginx",
        "owasp/modsecurity-crs:4-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4-nginx-202609140609",
        "owasp/modsecurity-crs:4.29-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.29-nginx-202609140609",
        "owasp/modsecurity-crs:4.29.0-nginx-202609140609",
        "ghcr.io/coreruleset/modsecurity-crs:4.29.0-nginx-202609140609"
      ],
...
      "tags": [
        "owasp/modsecurity-crs:3.3-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:3.3-nginx-lts",
        "owasp/modsecurity-crs:3.3.10-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:3.3.10-nginx-lts",
        "owasp/modsecurity-crs:3.3-nginx-202609140609-lts",
        "ghcr.io/coreruleset/modsecurity-crs:3.3-nginx-202609140609-lts",
        "owasp/modsecurity-crs:3.3.10-nginx-202609140609-lts",
        "ghcr.io/coreruleset/modsecurity-crs:3.3.10-nginx-202609140609-lts"
      ],
....
      "tags": [
        "owasp/modsecurity-crs:4.25-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25-nginx-lts",
        "owasp/modsecurity-crs:4.25.1-nginx-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25.1-nginx-lts",
        "owasp/modsecurity-crs:4.25-nginx-202609140609-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25-nginx-202609140609-lts",
        "owasp/modsecurity-crs:4.25.1-nginx-202609140609-lts",
        "ghcr.io/coreruleset/modsecurity-crs:4.25.1-nginx-202609140609-lts"
      ],

You can see the differences between main and this branch using: docker buildx bake --print --file docker-bake.hcl.

📝 Walkthrough

Walkthrough

The PR renames CRS LTS entries, adds minor and timestamped LTS tags, restricts base and daily tags to latest, and documents dated LTS tags with Nginx examples.

Changes

LTS tag generation and target selection

Layer / File(s)	Summary
Version entry and tag helper updates docker-bake.hcl	The configuration renames previous-lts to v3-lts and lts to v4-lts. The lts-tag helper adds minor and timestamped LTS tags.
Apache and Nginx target conditions docker-bake.hcl	Apache and Nginx emit base and daily tags only for latest. They emit LTS tags for v3-lts and v4-lts.
Documented dated LTS format README.md	The README documents optional YYYYMMDDHHMM dates before the -lts suffix and adds dated Nginx examples.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Suggested labels: release:breaking

Merge Risk: 🔵 Low · up to c46a1

Users copying the dated README examples may request tags that the current configuration does not produce; updating the examples is a small documentation fix.

Full details: Ai Contribution Disclosure

Explanation

The PR body contains only ## Summary by CodeRabbit and an auto-generated coderabbit.ai comment. It has no lowercase ## ai disclosure, ## what, ## why, or ## refs sections. The body also contains an explicit AI-tool signature line, which this check flags. The review-scoped diff is a real README/docker-bake.hcl change, not a trivial typo or version bump.

Resolution

Update the PR body with lowercase ## what, ## why, and ## refs sections. Add ## ai disclosure with concrete values for **tools used** (model and version), **assisted with** (the exact generated work), and **review performed** (specific verification). Remove the CodeRabbit auto-generated signature/comment and any Co-Authored-By or other AI attribution lines.

I'd keep "previous" in the name. Once we release the next LTS version, both will be from "v4" and we'll have to call them "previous-lts" and "current-lts" anyway.
