registry: add gem backend for bashly

[jdx]

Summary

• Add gem:bashly as the primary backend for bashly
• Keep asdf:mise-plugins/mise-bashly as a fallback
• Add test command for bashly

The gem backend is simpler and doesn't require a separate plugin since mise has native gem support.

Test plan

• Tested locally with mise x gem:[email protected] -- bashly --version

Note

Gem backend now returns remote versions oldest-first; registry updates bashly test to use --version.

• Backend
  • src/backend/gem.rs: Reverse order of versions in _list_remote_versions so parsed gem info results are returned oldest-first.
• Registry
  • registry.toml: Update tools.bashly test command to use bashly --version.
