IRRd documentation format fails presentation with many browsers about irrd

[dhutchin-ctl]

I don't know if this is a problem with the stuff in irrd/docs, or something at readthedocs.io. But I send people to the documentation every couple of weeks and it is very frustrating not to be able to render the items near the bottom of the left column. I can "control + '-'" a bunch of times, but that seems like the wrong solution. If the problem is with readthedocs.io, then we need to get a ticket filed with them. Not being familiar with how readthedocs works, or IRRd's use of it, I don't think I should be the one to file a bug report at https://github.com/readthedocs/readthedocs.org/issues

It's a problem with the sphinx theme used to render the doc: https://github.com/irrdnet/irrd/blob/main/docs/conf.py#L92

I had noticed it being a bit funky, didn't know it was this annoying in some browsers.
