Drop Python 3.11 from CI matrix

QCoDeS already requires Python >=3.12. This PR updates the CI
configuration and applies pyupgrade fixes:

- Updated pytest.yaml: removed 3.11 from matrix, min-version test now uses 3.12
- Updated docs.yaml: removed 3.11, gh-pages deploy uses 3.12
- Updated upload_to_pypi.yaml: build uses 3.12
- Removed obsolete pyvisa-sim deprecation warning filter (was only needed for 3.11)
- Bumped minimum dependency versions for Python 3.12 compat: numpy>=1.26.0, pandas>=2.1.1, pyarrow>=14.0.0, h5py>=3.10.0, h5netcdf>=1.3.0, pillow>=10.2.0, matplotlib>=3.8.0, scipy>=1.12.0
- Applied ruff pyupgrade fixes (UP040 TypeAlias->type, UP046 Generic->type params)
- Added noqa: UP046 for 13 complex multi-inheritance generic classes
