feat(tooling): section menu, links, blockquotes and content boxes

[hugomrdias]

This PR improves a couples of things

Depth slider css

Blockquotes now have proper background

Figures and embeds now have permalinks

Figures and embeds look the same

Embeds integrate all the elements inside same box as Figures

Section Menu

Now each section has a menu to aggregate all the info like state, audit, github edit link and unique identifier and more in the future like tests etc.

Check https://bafybeiexx7iex3upkzf76svkvvwhlg6xh6sxh5tq4k2t5hdvcjtsq63iuy.on.fleek.co/test/ to play with these new improved components.

Even faster CI without Go and fully on Fleek

Github action now only need node js and just run build and test scripts.

Other small stuff

• Remove multilang files
• CSS tweaks
• New system ui fonts
• Better permalinks
• All new svg icons, using svg symbols refs for perf

Great set of improvements! Makes it look much better!

@hugomrdias the conflicting file (proof_of_spacetime_parameters.org) has now been removed by another PR that has just been merged. The edit to that file is minor (typo). I suggest just ignoring it from your commit to resolve the conflict.

I've not had time to review the implementation, but the changes look beautiful!

The section heading menu is a neat idea. The icons could use a little more space and there is an overflow issue (in FF at least)

[yiannisbot]

Ahh, didn't spot the issue that @olizilla brings up - it works very nicely in Chromiums with a horizontal slider

One thing that seems a bit wonky is that the popup table/legend does not disappear when clicking elsewhere on the page or at another legend. The result can be that there are two overlapping ones. Minor thing, but would be nice to have fixed if it does not require a major amount of time.
