readthedocs build is broken; needs python version update

[mperrin]

I noticed that all our builds on readthedocs have been failing for the last nearly two months. since March 28. Error is about Python version, see below:

@BradleySappington might you be able to lend a hand with debugging this, please?

python -m pip install --upgrade --upgrade-strategy only-if-needed --no-cache-dir .[docs]

@mperrin - Part of the release this week is a version update for webbpsf to be >=3.10 which will fix this, I'll verify all is building properly before doing the release.

[mperrin]

Great, thanks. Sounds good.

Whenever we do get it building on readtheeocs before the release I’d like to try to do a check of the docs then for any rendering or formatting issues etc.
