Changes

avoid deprecation of Read the Docs

builds on readthedocs are currently failing, so this is an attempt to remedy this

Reading the readthedocs documentation, I think that what we had would still work. However, I provided an alternative in case the docs/requirements.txt is necessary. Additionally, from one of the examples on their documentation of the requirements file, another way is to add an install option to python as shown below:

python:
  version: 3.8
  pip_install: true
  install:
    path: ..
    extra_requirements: 
      - docs

which should similarly run pip install ..[docs] during building and is what is needed.

Thoughts?

I will try to mirror the attune configs setup, since they are still working well.
