docs: correct Go version requirement for building from source

[M. Gschwandtner (dontWatchMeCode)]

Summary

The Building from source section currently states that Go 1.20 or later is required, but the current go.mod in shopware/shopware-cli declares Go 1.26.4 as the minimum version.

Building with Go 1.20 fails while parsing go.mod, before dependencies can be resolved:

go: errors parsing go.mod:
/src/go.mod:3: invalid go version '1.26.4': must match format 1.23

This change updates the documented requirement to match go.mod.

Checklist

• I reviewed affected links, code samples, and cross-references, including PageRef references where relevant.
• I added or updated redirects in .gitbook.yaml if pages were moved, renamed, or deleted.
• I updated .wordlist.txt (and sorted it) if spellcheck flags new legitimate terms.
• Any required dependent changes in downstream modules have already been merged and published.
• This pull request is ready for review.

Notes

I used “Go 1.26.4 or later” to match go.mod exactly. Writing “Go 1.26 or later” would also include versions 1.26.0 through 1.26.3, which do not satisfy the declared minimum.

Alternatively, the documentation could refer readers directly to the version declared in go.mod to avoid duplicating a value that may become outdated.
