feat: Add team option to author filter

[robinmayerhofer]

Goal

Add a way to change behavior based on team membership.

This PR adds the team option to the author filter.
If the team is set, then it is verified that the author is part of the team, otherwise, the filter fails.

Together with #695, this enables checking whether an author is not part of a team.

How

I added team: 'string' to the supported settings of the author filter.
Then, I added a TeamProcessor that uses the existing functionality for Teams from the validators to check whether the user is part of the team.

Hi @shine2lay - this is another small feature, I rebased it on top of master after the previous PR was merged 🙂
