Allow direct specification of Python requirements in .readthedocs.yaml

[mcarans]

Thanks for a useful project. Currently you can specify Python requirements in a file and put the path in .readthedocs.yaml. I want to suggest specifying requirements directly in .readthedocs.yaml to reduce the number of configuration files needed eg. something like

version: 2
mkdocs: {}  # tell readthedocs to use mkdocs
python:
  version: 3.7
  install:
  - dependencies: 
     - "pydoc-markdown"
     - "readthedocs-custom-steps==0.5.1"

Hi! Thanks for opening this issue. We already talked about this in #5572 (comment). That issue has a long discussion about an un-related thing but ends mentioning the support to install packages directly from the YAML.

Looks like a duplicated of #5572 then?

Closing, discussed in #5572
