Allow disabling Thebe

See original GitHub issue

Description / Summary

I’m looking to optimize a jupyter-book. Looking at Google PageSpeed Insights, it looks like loading the thebe javascript from unpkg has a significant impact on page performance:

However, I don’t need thebe for my use case (I don’t have interactive cells). I want to disable thebe. AFAIK, that’s not possible in _config.yml (I can enable an extra extension but not disable an existing one). I would like to be able to explicitly disable thebe so I don’t load a 400KB javascript file when I don’t need it for my book.

Value / benefit

It would allow my book and others that don’t rely on the thebe functionality to disable it, improving the performance of their books.

Implementation details

I believe in addition to extra_extensions, there could another key in the sphinx config, disable_extensions, for this use case.

Thebe is now lazily loaded only when people explicitly click for it, so this should now be resolved! (ref: https://github.com/executablebooks/jupyter-book/pull/1634)

This issue is not only related to performance, but also to GDPR compliance. #797 addresses GDPR, #1625 tackles the conditional load.
