Rye support

Maybe I'm late to the party, but I started using rye recently and really like it. Some ideas for how to add support for it to this extension:

• Find <projectdir>/.venv to show in the interpreter dropdown, and maybe default to it?
• Automatically determine if rye fmt is available and use it if nothing else specified (and pass extra arguments correctly, i.e. after a --)
• Same for rye lint as above
• New Rye options section for python version and maybe setting up scripts? https://rye-up.com/guide/pyproject/#toolryescripts
• Commands for running rye sync, rye lock, etc.
