confusion noise functions not showing up in docs

[dbkeitel]

Which documentation page is causing an issue?
https://legwork.readthedocs.io/en/latest/modules.html#module-legwork.psd

What is the problem?
The LISA/TQ function documentations refer to legwork.psd.get_confusion_noise() but that identifier is not clickable, and I can't actually find that function (nor the specific implementations of confusion noise) anywhere in the API docs.

Suggested solution (optional)
The docstrings in https://github.com/TeamLEGWORK/LEGWORK/blob/main/legwork/psd.py look valid to me, so maybe the functions need to be added manually somewhere to sphinx...?

Ah nice catch! Sphinx only makes docs for functions in the all list at the top, so I just need to add them to that, will do!
