Enable pre/post processing on coverpage and sidebar

[gigaga]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch [email protected] for the project I'm working on.

The hooks beforeEach and afterEach are not used for cover neither sidebar rendering, so, any plugins cannot be used.

Here is the diff that solved my problem:

Hi @gigaga, if you make a pull request with the change we can evaluate it. I think it would be nice to be able to hook into any markdown rendering (f.e. also sidebar).

Hi @trusktr , I completed for sidebar rendering ;)

No, just this diff file 😉
