Bundle OFRAK docs so they always match GUI version

[whyitfor]

What is the use case for the feature?
As an OFRAK User, I want the OFRAK GUI to point to a local version of the docs that are build with the OFRAK GUI.

This will ensure that the docs are always up to date with the GUI version I am using, and will enable using OFRAK Docs without needing an internet connection.

Does the feature contain any proprietary information about another company's intellectual property?
No.

How would you implement this feature?
Consider building and bundling the OFRAK docs with the OFRAK server. This would mean that:

• PyPI version has docs in it?
• Docker image GUI references docs that are built when the GUI is built

Are there any (reasonable) alternative approaches?
Perhaps.

Are you interested in implementing it yourself?
Maybe.
