One-off build for rustworkx sdist and retworkx

[IvanIsCoding]

Related to #1492

I tested this locally and it worked e.g. python setup.py sdist passes.

For retworkx, it had more to do with the dist being in the wrong path

In theory this is deprecated, but so is retworkx so I think it will be fine

We probably should move the sdist creation to using python -m build --sdist for rustworkx.
When I test this locally it's able to build the sdist without errors like the CI job had.

The build isolation from build probably won't work for retworkx because that's a bit more special but that's ok.

You should undo this change, we don't want to forget about this. After this PR merges we can trigger the wheel build with a throwaway branch that we do as a one shot branched off of stable/0.17's HEAD. We'll also need to relax the release protection to enable triggering from a branch but we can do that in a one off.

I added an if condition to check that the date is today, does that work?

[IvanIsCoding]

@mtreinish I updated rustworkx's command to be python -m build --sdist.

For the one-off branch: I don't want to create yet another branch. Maybe we can reuse stable/0.17? I just added a check for today's date. That way we cannot trigger it by accident on the future.

@mtreinish I tested that the content of this PR is uploadable: rustworkz. I had to change x -> z because we already had a test upload of 0.14.1.

https://test.pypi.org/project/retworkx/0.17.1/ also worked.

I think we can merge this just to unblock users that opt for pip install --no-binary. I will update the date in the GitHub workflow such that it only runs on September 8, 2025 (this Monday).
