Jax: Broken docs check

[JuliusKunze]

The docs/readthedocs.org:jax check fails across PRs lately, i. e. here. The only error in the log is

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

myst-parser 0.12.8 requires docutils>=0.15, but you'll have docutils 0.14 which is incompatible.

We might be able to fix this by pinning versions in our docs?

This looks like it may have been fixed (by RTD?) in the past 16+ hours, as the doc builds have started passing again. @shoyer, any thoughts on whether to add the requirement anyway? PR is ready, but I can discard it too.

@froystig Thanks for bringing this up. This discussion on the readthedocs repo may be related - it seems to be pointing a similar issue at PiPy/pip: https://github.com/readthedocs/readthedocs.org/issues/7362#issuecomment-669828193

I'm going to close this because it indeed seems to have been fixed.
