Add CODEOWNERS file

[meyer]

Problem

Pull requests don’t get automatically assigned a reviewer.

Solution

Add a CODEOWNERS file to the .github folder that contains an entry for @sqrl-lang/everyone.

Result

This theoretically should make it so all folks in @sqrl-lang/everyone will get auto-added as reviewers for this repo. More info here: https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners
