Branch protection on main not adhering to best practices

Nobody has claimed this yet.

:wave: Hey there! It's [Changebot](https://github.com/mapbox/changebot), and I help repositories follow our [engineering](https://github.com/mapbox/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?

Please tag `@mapbox/security-and-compliance` on this issue if you have any questions

Review the main branch protection settings in the mapbox-navigation-android repository against the five best-practice items listed in the issue. Confirm whether each setting should be enabled and check with @mapbox/security-and-compliance when policy or permissions are unclear. Done means the settings have been reviewed and any needed adjustments are documented or applied.
