latest version forces python to 3.10 with errors

[davidhoover]

The step

mamba env update --name pydockrmsd --file condaenv/ci-cd.yml --prune

forced python to version 3.10, which gave errors with the next step

./scripts/install.sh

removing build/bdist.linux-x86_64/wheel
WARNING: Requirement 'dist/pydockrmsd-0.0.0-cp38-cp38-linux_x86_64.whl' looks like a filename, but the file does not exist
ERROR: pydockrmsd-0.0.0-cp38-cp38-linux_x86_64.whl is not a supported wheel on this platform.

I fixed this by pinning the python version:

conda config --env --add pinned_packages python=3.8

Also, munkres is missing from the requirements.
