Summary

Similar to how uv lock --upgrade updates all Python dependencies to their latest versions, it would be convenient if there was a single command that would update all currently installed uv-managed Python interpreters to their latest patch releases.

Example

If the user has Python 3.11, 3.12, and 3.13 installed, rather than having to type:

uv python install --reinstall 3.11
uv python install --reinstall 3.12
uv python install --reinstall 3.13

The user could type

uv python upgrade --all

This also removes the need for the user to remember which all versions are installed if they simply want to upgrade them all.
