Updating documentation to ReadTheDocs version 2 and MyST commonmark with sphinx markdown parser

Finally added a .readthedocs.yml file after being walked through it by the maintainer of MyST Parser

And got this build error:

ERROR: Directory ‘.’ is not installable. Neither ‘setup.py’ nor ‘pyproject.toml’ found.

Here’s my .readthedocs.yml that broke it, because i was following a model that didn’t match my simple setup:

version: 2
python:
  version: 3
  install:
      - method: pip
        path: .

This is what it needed to look like:

version: 2
sphinx:
  configuration: conf.py
python:
  version: 3
  install:
    - requirements: requirements.txt
