PR #20677 Review Summary

The PR replaces vague "Any version" supported-version labels with specific ceiling values ("Any version up to X.Y.Z") in the Pages build environment YAML files and updates the corresponding note in the docs. It also bumps Ruby to 3.4.7 and adds uv as a tool on the Workers build image page.

3 suggestions posted for @yomna-shousha:

1. Note visibility (Medium) — The "Supported versions" note only appears under Languages, but the Tools table also shows "Any version up to..." entries. Consider moving the note higher so it covers both tables.
2. uv row ordering (Low) — The new uv row could be grouped with other Python-ecosystem tools (after poetry) rather than between pipx and bundler.
3. uv environment variable (Low) — If uv supports version pinning via an env var, it should be listed for consistency with other tools.

No build-breaking issues, MDX syntax problems, or frontmatter errors found.

Working on a release to auto-update version releases so this draft hopefully should not be needed.
