Update readthedocs.yml

[berl]

make readthedocs config compatible with latest requirements

@berl I approved your PR, but the readthedocs.yml file might be missing:

# Build documentation in the docs/ directory with Sphinx
sphinx:
   configuration: docs/source/conf.py

If you don't think it is necessary, you can "squash and merge" the branch

After testing the changes, I got an error that needs fixing

This version failed to build and so I suggest the following for readthedocs.yml (below).

# Read the Docs configuration file for Sphinx projects
# See https://docs.readthedocs.io/en/stable/config-file/v2.html for details

# Required
version: 2

# Set the OS, Python version and other tools you might need
build:
    os: ubuntu-22.04
    tools:
        python: "3.10"

# Build documentation in the "docs/" directory with Sphinx
sphinx:
  configuration: docs/source/conf.py
  # You can configure Sphinx to use a different builder, for instance use the dirhtml builder for simpler URLs
  # builder: "dirhtml"
  # Fail on all warnings to avoid broken references
  fail_on_warning: true

python:
    install:
        - requirements: requirements/REQUIREMENTS-CI.txt
        - method: pip
          path: .

Thanks for the quick update.
I found a few minor issues when building from my fork, but my guess is that they are related to the Sphinx built and configuration.
I will address them in a separate PR
