snews-cs docs not building

[sybenzvi]

@justinvasel created a branch and PR (#90) to clean up broken docs generation. I merged it but I find offline that several of the pinned dependencies in doc/requirements.txt are not resolving properly, causing sphinx documentation to fail.

When I try to build the docs on RTD page, it fails here;

SNEWS_Coincidence_System/.readthedocs.yaml

Lines 19 to 22 in 0e4b8cb

	post_install:
	# Install dependencies with 'docs' dependency group
	# https://python-poetry.org/docs/managing-dependencies/#dependency-groups
	- poetry install --with docs

saying

ModuleNotFoundError: No module named 'six.moves'

Maybe it needs to be added here;

SNEWS_Coincidence_System/pyproject.toml

Lines 51 to 53 in 0e4b8cb

	[tool.poetry.group.docs.dependencies]
	sphinx = "<5" # Constrained by snews_pt
	sphinx-pdj-theme = "^0.4.0"

?

This PR #108 should fix it. I'll close the issue once it is merged
