Docs seem to be failing on cell in NotebookCollection.md. An ImportError is being raised for lxml— odd because it looks like it's a dependency in environment.yml. Didn't have this issue locally, maybe it's not being installed in readthedocs run?

nbclient.exceptions.CellExecutionError: An error occurred while executing the following cell:
------------------
nbs["metrics"]
------------------

Raises this:

ImportError: lxml not found, please install it
ImportError: lxml not found, please install it
