Evaluate current use of Ruby/Jekyll

[ottok]

Our current seravo.com/docs has served us well, but it might need a structural upgrade.

Biggest annoyances at the moment:

• Pages are not easy to render locally, the experience is much more archaic than e.g. compared to sites that use Hugo
• Instead of every article being a post with a date, they should be dateless pages so the "information architecture" would be correct.
• Our man pages are not part of the docs and there is no easy way to append them there.

I have been looking at how nice the Pydantic docs look like, and they have a built-in search (just like we need) with some additional features, and is build using Python and all build code and Github Actions are available publicly.

Articles are now pages and man pages have been hosted under seravo.com/docs for a while. I will take a look into the first point while updating the documentation: https://github.com/Seravo/docs/issues/69
