Add test for incorrect casing of `GitLab` and `GitHub`
The easiest way to do this is find a Gitlab
or a Github
and match on
incorrect casing. We can ignore lower-case names, as they're likely on
purpose, whereas mixed-case is incorrect.
- It makes more sense to have a
test
namespace with the HTMLProofer and GitHub/GitLab testing underneath - Report issues and then error out
Plus fix the existing incorrectly-cased findings.
Closes #206 (closed).
