AST-1500 Fix building python wheel on CI
- Use new quay.io casacore images.
- Install OpenBLAS in image since regular libblas.o doesn't supply cblas functions on the CentOS7 casacore images.
- Use latest schaapcommon, which removes a Boost include.
- Use pytest 7.x since 8.x doesn't work with pytest-lazy-fixture.
- Build wheels for Python 3.7 - 3.12.
- Also enable build wheels job on SKAO mirror.
