- our use-case for this is to ensure that people don't push to
`main` without running linting, as this can block CI from passing
until the linting issue is resolved
- however, it can become annoying to run linting on non-main branches,
especially when you just want to WIP some changes without caring for
linting
- generally speaking, anyone who creates commits on a non-main branch is
going to open them as a PR, so linting is run anyway
- this commit get the branch name and only runs linting if we're on
`main`
