Subject: [PATCH] Fix warning about SPDX license identifier

When running cibuildwheel 2.23.3 runs under Python 3.12, the following
warning would show up in the logs:

```
  /tmp/pip-build-env-ucihqcl8/overlay/lib/python3.12/site-packages/setuptools/dist.py:759:
  SetuptoolsDeprecationWarning: License classifiers are deprecated.
  !!

          ********************************************************************************
          Please consider removing the following classifiers in favor
          of a SPDX license expression:

          License :: OSI Approved :: Apache Software License

          See
          https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license
          for details.
          ********************************************************************************
```

This commit removes the license classifier and updates the `license`
keyword to use the SPDX license id.
