Describe the Bug

When I run sphinx_build with both myst_parser and myst_nb I get the following error. This does not happen with myst_parser only enabled.

File ".../python3.10/site-packages/myst_parser/sphinx_ext/main.py", line 49, in setup_sphinx
    app.registry.transforms.remove(SphinxUnreferencedFootnotesDetector)
ValueError: list.remove(x): x not in list

Expected Behavior

Based on the Jupyter Book configuration, it seems like you're only meant to enable myst_nb, not both myst_parser and myst_md. Does this issue occur with just myst_nb listed in the extensions?

No, then it works, thanks. However, I would prefer a more meaningful exception, as I assume that this mistake might be common.
