[docs] Aspire 13.5 stub: security dependency update (CVE-2026-46681)

[aspire-repo-bot]

Documents changes from microsoft/aspire#17539 by @dependabot.

What and why

This PR creates a stub What's new in Aspire 13.5 page that records the security dependency update shipped via microsoft/aspire#17539.

The source PR bumps npm packages across the repository (including the Visual Studio Code extension) and patches CVE-2026-46681 — a Prototype Pollution vulnerability in @nevware21/ts-utils (via objDeepCopy/objCopyProps using for...in without hasOwnProperty guards).

Target branch

Targeting release/13.4 — the latest release branch on microsoft/aspire.dev — because release/13.5 (from the source PR milestone 13.5) does not exist there.

Changes

• Created src/frontend/src/content/docs/whats-new/aspire-13-5.mdx — stub What's new page for 13.5 noting the CVE fix
• Updated src/frontend/config/sidebar/docs.topics.ts — adds Aspire 13.5 entry at the top of the What's new list

Note: This is a stub. As more 13.5 changes land, this page should be expanded with full release notes.

Source-of-truth branch mismatch — review skipped

Cannot verify this PR against microsoft/aspire.

PR base branch (microsoft/aspire.dev)	release/13.5
Matching branch in microsoft/aspire	does not exist
Latest release branch in microsoft/aspire	release/13.4 (4f2189335)
Source PR cited in body	microsoft/aspire# — merged to main, milestone 13.5

My review protocol requires using the matching microsoft/aspire release branch as the single source of truth for claim verification. Because no release/13.5 branch exists on microsoft/aspire yet (13.5 has not been cut), I cannot verify the API/CLI/config claims in this PR against an authoritative source code snapshot for that release.

Possible resolutions:

1. Re-target this PR to release/13.4 in aspire.dev if the documented behavior is already present in 13.4.
2. Wait until release/13.5 is cut in microsoft/aspire, then re-run review against that branch.

Skipping Phase B (doc-tester) as well — running it without the Phase A claim verification would produce an incomplete review per protocol.
