chore(docs): autogeneration of NoirJS docs

[signorecello]

Description

This PR adds autogenerated docs for NoirJS packages, using Typedoc

Problem*

We're spending way too much time changing function signatures and similar stuff. We should be able to rely on autogeneration for that.

Resolves #3199

Summary*

• Adds and configures two plugins to docusaurus in order to generate sidebars, and make the return of typedoc be formatted in markdown
• Exports types from noir_js and backend_barretenberg so they are documented, apparently this is the only way of documenting the types. I find Typedoc too opinionated, but afaik there's no better tool

Additional context

I hacked around a bunch of ignores here and there, they'd tipically be made private but for some reason they aren't so I'm manually ignoring them. Again, Typedoc expects code to be written in a certain format in order to be documented in a certain way

These docs builds fail and will continue to fail because they depend on other package's build processes. Unfortunately netlify doesn't really provide a way to define a better CI process.

However #3296 already solves this by building with the Github CI. So let's block this one until we merge that, and I'll figure out then

Is it possible to autogenerate links to the source code on github?

This is incredible. Thank you @signorecello!
