Deploy documentation to GitHub Pages

[yonch]

We created a gh-pages branch to this repository, and https://perfpod.github.io/memory-collector/ points to the README.md.

In this ticket, we create

• [ ] a docs directory in the repo
• [ ] an initial readme (can be the first few paragraphs of the README.md for now)
• [ ] an initial mkdocs.yml
• [ ] a GitHub Actions to publish to the gh-pages branch. There are instructions on the MkDocs page: link. This would probably involve using a good docker container and perhaps fetching the MkDocs dependencies.

I've had previous success with the following python deps:

mkdocs
pymdown-extensions
mkdocs-material
mkdocs-bibtex
mkdocs-awesome-pages-plugin

here is a reference mkdocs.yml:

site_name: 'PerfPod docs'
site_url: https://state-fu.com/docs
nav:
  - Home: 'README.md'
theme: material
markdown_extensions:
  - pymdownx.tasklist:
      custom_checkbox: true
  - footnotes
  - attr_list

plugins:
  - search
  - awesome-pages

We need a website too to apply for free credits.
