FR: Add support for uv tool upgrade --python <PYTHON>

[weihenglim]

It would be useful to have a way to reinstall/upgrade all installed tools to the latest Python version.

Currently we are able to reinstall all tools via uv tool upgrade --all --reinstall but are unable to specify the Python version. The workaround is to perform uv tool install --python <PYTHON> <PACKAGE> for all tools individually.

As an aside, it would also be nice if uv tool list displays the Python version that was used to install the tool (similar to how pipx list behaves)

Upgrading Python versions makes a lot of sense.

Why is the version important for you to see in uv tool list? Aren't most tools Python version agnostic?

Personally for me it just makes it easier to spot, at a glance, the tools that are stuck on an older version due to being installed by an old Python interpreter.

For example if I run uv tool install yt-dlp with a system Python 3.7, uv tool list will show the installed package as yt-dlp v2023.11.16. After upgrading the system Python to 3.12, performing a uv tool upgrade yt-dlp will result in a Nothing to upgrade message even though a newer version (v2024.8.6) is available for Python 3.12.

Hope that makes sense.
