[Caylipp]

I reviewed and tested this PR together with the 7z extraction support from #2177.

The Ruby commandlet is correctly registered and follows the existing LocalToolCommandlet pattern. The English and German help texts as well as the CHANGELOG entry are included.

Manual testing on Windows with the local build script was successful:

• ide install ruby successfully installed Ruby 4.0.6-1.
• ide uninstall ruby successfully removed the installation.
• Reinstalling Ruby after the uninstall was successful.
• ide ruby --version returned the expected Ruby version.
• ide ruby -e 'puts(%q[Ruby works])' successfully executed Ruby code and returned Ruby works.

Running ide ruby without arguments waits for input via stdin, which is expected Ruby behavior.

Good Job! Looks good from my side. I approve.
