Drop Python 3.11 from CI matrix

QCoDeS already requires Python >=3.12. This PR updates the CI
configuration to match:

- 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: numpy>=1.26.0, pandas>=2.1.0
