`uv run` supports python zipapp (#7289)
## Summary
`python` supports running a zipfile containing a `__main__.py` file, for
example `python ./pre-commit-3.8.0.pyz`.
See https://docs.python.org/3/using/cmdline.html#interface-options:
> <script> Execute the Python code contained in script, which must be a
filesystem path (absolute or relative) referring to either a Python
file, a directory containing a __main__.py file, or a zipfile containing
a __main__.py file.
and https://docs.python.org/3/library/zipapp.html.
Similar to #7281, this PR allows `uv run ./pre-commit-3.8.0.pyz` to
work.
## Test Plan
```console
$ curl -O https://github.com/pre-commit/pre-commit/releases/download/v3.8.0/pre-commit-3.8.0.pyz
$ cargo run -- run ./pre-commit-3.8.0.pyz
```
