Clean up CI and drop py3.7

[blink1073]

Python 3.7 is EOL. Clean up CI and test all current Python versions.
Update readthedocs config.

Fixes #230. Fixes #232

@akhmerov can you please add blink1073 to https://readthedocs.org/projects/jupyter-sphinx/ so I can set up the PR build integration?

[12rambau]

any reason why you are not testing all python version on ubuntu and only latest on extra platform (mac and windows). This is what I have been doing so far in other repo but now I'm questioning myself....

[blink1073]

Updated!

Fix #230

@blink1073 done!

[12rambau]

@blink1073 done!

@12rambau I see this:

You are right, I'm "borntobealive" over there (same knight avatar if it helps)

@blink1073 another RTD-related issue: the webhook integration listed here needs to be updated with a secret, and I cannot do this because of not having sufficient github permissions for this repo.

[blink1073]

Thanks @akhmerov, I created a new webhook, and it is working now

[12rambau]

@blink1073, Is this ready to merge or you have other requests related to the build ?

[blink1073]

you have other requests related to the build ?

Yes, but in follow up PRs. :)
