Update scikit-build-core

[JeanChristopheMorinPerso]

We received an automated from PyPI:

This email is notifying you of an upcoming deprecation that we have determined may affect you as a result of your recent upload to 'MaterialX'.

In the future, PyPI will require all newly uploaded source distribution filenames to comply with PEP 625. Any source distributions already uploaded will remain in place as-is and do not need to be updated.

Specifically, your recent upload of 'MaterialX-1.39.2.tar.gz' is incompatible with PEP 625 because it does not contain the normalized project name 'materialx'.

In most cases, this can be resolved by upgrading the version of your build tooling to a later version that supports PEP 625 and produces compliant filenames.

If you have questions, you can email [email protected] to communicate with the PyPI [email protected] to communicate with the PyPI administrators.

So this PR does exactly what this email is asking about.

While updating, I took the decision to drop the custom plugin and instead rely on a built-in regex plugin to extract the version from cmake. This is much faster and won't tie the project to a specific scikit-build-core version.
