Update Python versions in CI, remove macos-intel.

Python 3.9 reached its end of life on October 31 2025.
Changing tested versions from 3.9 and 3.12 to 3.10 and 3.13.

Also, there is an issue with the llvmlite package on macos-15-intel.
It is no longer available from PyPI for Python 3.10 and above. As a
consequence we are removing testing on this platform as the minimal
tested Python version is now 3.10.
