"Edit on GitHub" links are broken

[kappa]

Readthedocs-hosted doc pages for individual rules all have links at the top right corner that are broken.

Example: https://fixit.readthedocs.io/en/latest/rules/NoAssertEqualsRule.html has a link to https://github.com/Instagram/Fixit/blob/master/docs/source/rules/NoAssertEqualsRule.rst which does not exist.

@kappa these are using absolute links not relative links. Does not work.
