Extend test "uv add magika.whl" to windows runner

[reyammer]

We recently updated our python github workflows to test that the magika package/wheels can be installed with uv add (in addition to pip install magika). To test this, we use a one-liner that currently works only for ubuntu and macos. We need to extend the one-liner (or add another one) so that it also works for Windows.

These are the workflows to update:

• [ ] https://github.com/google/magika/blob/main/.github/workflows/python-test-published-package.yml
• [ ] https://github.com/google/magika/blob/main/.github/workflows/python-test-published-rc-package.yml
• [ ] https://github.com/google/magika/blob/main/.github/workflows/python-build-package.yml

@reyammer I'd like to take a stab at this

Go for it, thanks! Assigned it. The idea would be to add another if, and for windows use some powershell-like syntax to implement the same one-liner. Let me know if you have questions or something is not clear.
