Linters are only ran on main

[xibz]

With all the efforts being put into linters and cherry picking them to other branches, I noticed that none of them were being ran.

#223

While it isn't too big of a deal not having any linting on the cherry pick branches, but since it's easy enough to turn on and will ensure consistency between the pick branches vs main, I would opt to turn them on.
