Fix dependency conflicts in pyproject.toml

[dgmcdona]

Closes #1546

This makes three changes to fix dependency resolution

• Fixes a bug where the sphinx version is unresolvable, and pins it to
  8.0.2 (the minimum version required by the minimum version of
  sphinx-autodoc-typehints)
• Lowers the required version of pefile in order to allow us to use
  the pyinstaller version specified in the dev dependencies
• Bumps the python version to 3.10 in order to support sphinx 8.0.2

I know bumping the minimum Python version is not desirable, but I wasn't sure which sphinx/sphinx-autodoc-typehints versions would be acceptable due to my unfamiliarity with our doc requirements. We can lower those if an acceptable version can be found that supports python 3.8. There isn't a way to specify different required Python versions for different sets of dependencies within pyproject.toml.

I reverted the Python version bumps and found the highest versions of sphinx-autodoc-typehints and sphinx that still support Python 3.8. Installing those versions and building the docs with cd doc; make html seemed to work fine, although there are some existing syntax errors within the documentation that don't cause the build to fail.

I also looked through the git history to see if there was a reason that we require such a high version of pefile and couldn't find one, it seems that it was bumped in this commit
