@Venefilyn, the file at .github/workflows/pr-docs-check.yml also needs to be updated with the pip install -r ....

Also, I see that you created a docs/requirements.txt. In the past, I've added the sphinx docs dependencies to each .devcontainer/*/requirements.txt, maybe to keep consistency all around we should remove that dependency from those devcontainers requirements and actually place them in a single place, like the docs/requirements.txt you created? I think that would make it more organized.

Okay @r0x0d should work now. Changed around the syntax a bit for working directory
