Mimesis: Use type hints in docs

[sobolevn]

Connected to https://github.com/lk-geimfari/mimesis/issues/258

There is a plugin for sphinx to grab type hints into autodocs: https://github.com/agronholm/sphinx-autodoc-typehints

I guess it should be used.

I'll try to make this work, if you don't mind :)

[sobolevn]

Make sure you are in sync with https://github.com/lk-geimfari/mimesis/pull/260

[DefaultSimon]

I have already made the necessary changes to convert :rtype: to type annotations and enable the sphinx extension, should I add annotations for parameters like in #260 as well?

[sobolevn]

@lk-geimfari could you please help @DefaltSimon ?

[lk-geimfari]

@DefaltSimon Yeah, sure. We work on type hints in type-hinting branch.

[DefaultSimon]

Sure, I'll submit a pull request to that branch when I finish builtins and the base mimesis directory.
