fix(ci): restore Homebrew formula auto-update (#502)

The update-homebrew job was removed when cargo-dist regenerated release.yml.
This restores automatic formula updates on release.

- Uses mislav/bump-homebrew-formula-action@v3.2
- Updated tap to redis-developer/homebrew-tap
- Added note about manual maintenance since cargo-dist overwrites this file
