Numpy fixes and changes to testing workflow

[phoebe-p]

• Fixed deprecated Numpy functions and changes testing workflow to remove old Python versions (now testing 3.9 - 3.12)
• Update Github actions versions
• Use a specific version of spin (0.9) which does not cause issues with the --ignore flag for including test_examples.py
• remove S4 installation for MacOS ARM/M1, since this no longer works for some reason (complaining about not finding boost header files even when homebrew path is explicitly linked in Makefile.m1)
• Changes to phoebe-p/S4 to stop compiler errors with Interpolator type
