remove the backslash escapes and typehint fragments in the API docs

[keewis]

The reason for those fragments is that napoleon and numpydoc somehow conflict with each other. From a quick glance I couldn't find anything that breaks without numpydoc, but I might be missing something.

For reference, here's the new API page.

• Closes type annotations make docs confusing #3178
• Passes isort -rc . && black . && mypy . && flake8

Nice! the apply-ufunc signature is readable again. Should close #3178

[keewis]

is the (seemingly random) distributed failure a known issue?

[keewis]

there is a difference between the versions with and without numpydoc: the reference pages for the ufuncs don't show the signature. Since that would always have been (*args, **kwargs) we don't lose anything, I guess?

Great! Thanks @keewis !

[dcherian]

: the reference pages for the ufuncs don't show the signature.

I think this is a relatively minor issue for a really large improvement in signatures for other functions

[keewis]

if there are no issues without numpydoc, should we merge?

[dcherian]

SOudns good to me!
