Branch protection on main not adhering to best practices

[mapbox-github-ci-issues-3[bot]]

:wave: Hey there! It's Changebot, and I help repositories follow our engineering best practices. My magic wand found some things I wanted to highlight for your review:

Item	Current status	Best practice guidelines
main branch protection: Dismiss stale pull request approvals when new commits are pushed	Unchecked	Checked
main branch protection: Require review from Code Owners	Unchecked	Checked
main branch protection: Restrict who can dismiss pull request reviews	Unchecked	Checked
main branch protection: Require branches to be up to date before merging	Unchecked	Checked
main branch protection: Restrict who can push to this branch	Unchecked	Checked

Can you take a look at these best practices and make any adjustments if needed?
