Docs request: `github` remote style looking in subfolder

[jamesbraza]

Problem

I am reading through https://nitpick.readthedocs.io/en/latest/configuration.html#remote-style as of 0.34.0.

I am trying to figure out how to have github remote get a style from a subfolder.

Possible solution

How can one get a config from a subfolder? Can we add docs for that?
