Fix README tag pollution from update script (#573)

* fix: Improve README tag generation to reduce clutter

- Modified update.sh to only show the latest and stable versions
- Removed duplicate major.minor version tags
- Changed from listing all versions to showing only the most relevant tags
- Fixed jq query to properly detect stable version using index() instead of contains()

This significantly reduces README pollution by showing only:
- The latest experimental version with its tags
- The current stable version with its tags
- One entry per major.minor version for older releases (removed from this commit)

Before: 60+ lines of tags with many duplicates
After: 2 lines showing only latest and stable versions

* fix: Address shellcheck warnings about subshell variable modifications

- Changed from pipeline to process substitution to avoid SC2030/SC2031 warnings
- Variables modified in the while loop are now properly preserved
- This ensures readme_tags modifications are not lost in subshells
