chore: create CODEOWNERS

[cedoor]

Description

The CODEOWNERS file defines individuals or teams that are responsible for code in a repository. Code owners are automatically requested for review when someone opens a pull request that modifies code that they own.

As a general rule, at least 1 review by one of the code owners in new PRs is always required.
