Allow "uvx python" to execute Python like "uv run python"

[ksamuel]

Right now, if you run uvx python, it can fail. Even uvx -p 3.11 python will fail to start a Python shell on Windows or Ubuntu because the command doesn't map to a python executable.

However, uv run python works, no matter where you execute it.

It's counter-intuitive, one would expect you can run the installed you installed with uv from uvx.

What's more, it would be a useful feature to be able to do uvx -p 3.12 --with pendulum python to test how this lib works in python 3.12 quickly.

Right now, one has to do uvx -p 3.12 --with pendulum ipython which is fine if you are familiar with the Python ecosystem and uv limitations, but probably not for beginners, for whom uv is the biggest boon.

Are you in need of such a function

uvx -p 3.12 --from pendulum python

Edit:
As for uvx python, I believe it's a duplicate of this issue (#7430).
