[jpvajda]

To make it easier to support users and maintain this project we should automatically move issues to the project board, and also notify the maintainers of the project via github notifications when an issue is created. this may require setting code owners on the repo.

Acceptance Criteria

• Define which people are code owners
• create a code owner file
• add a github workflow to move issues to the project board and also notify the code owners of the issue.
