Add support for caching `uv`

[akx]

Description

This PR adds support for cache: uv, for the new uv package manager.

Check list:

• [ ] Mark if documentation changes are required.
• [ ] Mark if tests were added or updated to cover the changes.

[akx]

I'll add tests etc. if there's any interest in this – considering my other PR #762 has not been looked at in a quarter of a year, I'm not holding my breath yet 🙂

This should be merged: uv is becoming quite popular.

Please let me know if there's anything you need from the Astral team.
