fix: handle uvx like uv

See #818 (comment).

I'm still seeing the warning

nox > Warning: uvx is not installed into the virtualenv, it is located at /Users/me/.local/bin/uvx. This might cause issues! Pass external=True into run() to silence this message.

I used uvx --with git+https://github.com/wntrblm/nox.git@refs/pull/920/head nox -rs <session>

PS: I also had to change nox.options.sessions to be a list since it was erroring with a tuple, so we should call it out in the future release notes.

Oops, I thought about that when I started, but forgot about it by the time I added a test. I'll add it. Though I don't remember where we handle this for "uv".

Where was nox.options.sessions a tuple?

In my noxfile.py. I see the examples in https://nox.thea.codes/en/stable/config.html all use lists, so maybe only I was in the wrong 😅

Can you try now? I'm looking into the over-validtion issue.

Aha, that did it!
