fix broken version selector in docs

[pacrob]

What was wrong?

Since v6 released, the version selector at the bottom of readthedocs hasn't worked

How was it fixed?

sphinx_rtd_theme listed jquery not loading as a known issue. Applied their fix.

Todo:

• Add entry to the release notes

@pacrob what's the best way to test this? I'm not sure that the readthedocs builds from PR # ever had the issue. I'm seeing it working with some PRs that are currently open.

Not sure about testing, short of some kind of webpage testing. Docs for 2882, 2886, and 2887 come up with it not working for me, where 2883 weren't working yesterday, then started working when I made the change to conf.py.

Those are also not working for me but 2857 and 2861 are. It would be nice to have some other way to test this but I'm inclined to merge it in and see what happens since it wouldn't hurt anything and looks to be the proposed solution, as you linked above.

I'd say let's give it a shot and retract the newsfragment if it doesn't fix the jquery injection and go from there.
