Python requirements need to be updated for latest Slicer python version

[jamesobutler]

Similar to what is needed at DCBIA-OrthoLab/MFSDA_Python#26

Slicer recently upgraded from Python 3.6.7 to Python 3.9.10 in Slicer/Slicer@34e48e8. There are now observed build errors of the ShapeVariationAnalyzer Slicer extension as seen at https://slicer.cdash.org/viewBuildError.php?buildid=2618477. This is because the python requirements file in the repo is including hashes that are only for Python 3.6 wheels. These need to be updated for Python 3.9 wheels which also means the actual version of packages here will need to be updated as some older versions simply don't have Python 3.9 wheels because that version was released before Python 3.9 was even released. For example scikit-learn==0.23.1 does not have Python 3.9 wheels available from PyPI (see here).
