Drop Python 3.8 and 3.9 support

Updates both setuptools-scm and vcs-versioning to require Python >= 3.10.

Changes:
- Set requires-python to >=3.10 in both packages
- Remove Python 3.8 and 3.9 from classifiers
- Update CI test matrix to remove Python 3.8 and 3.9

This aligns with the PEP 639 compliance which requires setuptools >= 77.0.3.
