ReadtheDocs configuration yamls need to be updated to use poetry 2.

[mjohanse-emr]

Bug Report

We're using poetry 2.1.4 as the default poetry version now. However, the ReadTheDocs.yaml configuration files are still installing poetry 1.8.2. We should update those configurations to match the default poetry version used by the rest of the github actions.

Repro or Code Sample

jobs:
    post_create_environment:
      - pip install poetry==1.8.2

Expected Behavior

Should use poetry 2.1.4

Current Behavior

Uses poetry 1.8.2

Possible Solution

Update the version we install
