historic docs v2

[sh-rp]

Description

PR for adding historic docs without checking these historic docs into the repo. Mechanism:

• Discover all tags and find all the most recent minor versions (above a certain configurable threshold)
• Check out each tag in a separate folder and build the docs at that point in time and copy them into the main project
• Current repo version will be the devel version, so we should only deploy docs from devel.
• Will deploy the master branch as the version for the current highest release instead of the tag
• Prevents indexing by google via header tags
• Ensure algolia does not index historic versions (via algolia console, you can explicitely say to respect noindex header tags)

TODO after merging:

• Switch of devel deployment on netfliy, we might need to update the paths in the website that point the /docs/devel path to that deployment.
