Add workflows and dependencies to build and deploy versioned docs

[JaroCamphuijsen]

fixes #123

The versioned documentation of all previous minor releases has already been deployed on www.mibipret.github.io/mibiscreen

Any PR's and commits to the main branch (including the opening of this PR) will trigger the build and deployment of a 'develop' version of the documentation.

You can also test locally by

1. updating your local gh-pages branch
2. on this branch (issue123_versioned_docs), installing the new documentation dependencies with pip install .[doc],
3. on this branch, running mike serve

hey @raar1 there is a familiar sonar cloud error in the workflow runs of this PR that I think you know more about. I also seem to remember that you had a really good time solving that! Can you maybe do it again?

@AlrauneZ the other failed runs (the python package ones) seem to be related to the panda's issue you mentioned earlier. Did you already have a solution for #124 ??

I've fixed the token issue and added instructions to the developer README on how to fix it
