Protect the main branch

[joshbressers]

The main branch in this repository is not protected (I accidentally committed to it earlier today). We should have a branch protection rule to prevent this from happening.

@david-a-wheeler @jorydotcom can one of you help with this?

thanks in advance

@joshbressers - done, added branch protection on "main". I included a requirement for a reviewer - let me know if that's too much, or if you want any other changes.

That sounds perfect, thanks!
