Documentation: Integrate odoc to generate documentation

[ulrikstrid]

Might want to have a look here on how to generate the docs in CI: https://github.com/esy-ocaml/hello-reason/blob/master/.ci/utils/create-docs.yml

@samatar26 (@bryphe, @samatar26 is a friend who is interested in helping out, he's a JS developer, new to reason), this might be a good issue for you to start with if you want to help out, might need to have a look at the docs for odoc and see how to integrate it here then maybe find some comments and change them to the right ones (its in the docs) and see if you can output some docs

The infra is actually done in #251, when we land #272 with some actual docs I think this can be closed

We've been also trying to research this for Brisk. It'd be great to use the same infra.

We actually have some basic docs now: https://www.outrunlabs.com/revery/api/revery/
