Fix inheritance diagram

[bluthej]

Closes #2041.

I think this should do the trick, as per this section of the readthedocs documentation.

I wasn't able to actually test this out myself because I couldn't find a way to test this locally, even in the RTD docs.
It looks like they make users rely on Pull request previews in order to test the config. Are those activated for this repo?

Thanks a lot for looking into this. I have just enabled pull request previews. That's a really good suggestion. Can you try and force push this change, so we can test if this actually works?

[bluthej]

Sure thing! I just did and then looked at the docs/readthedocs.org:jedi check, clicked on Details which opened the preview and the diagram is showing correctly :)

Thanks for the kind words, I appreciate it!
I've been using jedi everyday for the past year and a half through python-lsp-server, so I'm very grateful that it exists and if I can contribute back even on a very small thing like that I'm very happy :)

Thanks :)
