Pinning package requirements for readthedocs

[adcroft]

Minor version updates to multiple packages used in the generation of the documentation introduce dependencies needing Sphinx >= 5.0, which breaks the sphinx extensions we use in documenting the MOM6 APIs. I have added versions for all the packages needed to keep things working with Sphinx4 for now, but we really do need to find a way to work with the newer versions.

Could you say more about the Sphinx4 extensions that we are using in MOM6 that are problematic with Sphinx5. How widespread are they, and how much work would it be to avoid using them?

This discussion tab is a bit out of date, but it's probably the last time we really understood the problem: mom-ocean#1378

Adding this in, but we need to get our docgen problems sorted out. At the least, things need to work with the latest versions of our toolchains (doxygen, sphinx, and sphinxcontrib packages).
