update fpca references

[aleexarias]

Resolves #634

The reference in _fpca is moved into the class docstring instead of the private function it was on, using footcite/footbibliography

• I have performed a self-review of my code
• The code conforms to the style used in this package
• The code is fully documented and typed (type-checked with Mypy)
• I have added thorough tests for the new/changed functionality

In general it is way better, but I am still unsure. In particular, I would check with Alberto if the page numbers are really necessary and it is not enough to just use the chapter name between parentheses or something like that. Otherwise it feels a bit too verbose.

Apart from that, check the comments.

[vnmabus]

Just a small error (probably a typo). Fix that and it is done 😊

[vnmabus]

I don't know why you added the last two commits, but please drop them (with interactive rebase) as they are probably unnecessary and they are breaking the tests.

[vnmabus]

There is a conflict. Maybe you can rebase your changes on top of the develop branch to fix it.
