codeowners: add team members

[0cc4m]

This reverts commit cf45437.

Overview

The problem is that Github organization teams are invisible to anyone who is not a member of the organization. This unnecessarily obscures who is responsible for what. We can still use teams manually for pings or review requests.

I manually went through the changes and fixed the cases where something else was edited in the file.

Requirements

• I have read and agree with the contributing guidelines
• AI usage disclosure: NO

Hmmm, that's a bit silly, it's really useful to have teams automatically assigned for reviews, not to mention not having to update CODEOWNERS whenever a team is updated...

Anyway, we should not revert it back to what it was, but rather expand the teams into its members if we're going to do this.

We can do that, I wasn't sure which changes were only due to teams. Maybe it's possible to keep the team + the maintainer members of it in the file?

Perhaps a compromise; keep the teams, but add one main responsible member? If that works...

Can we change visibility of some teams which do code reviews? Like the backend teams

They are already set to visible, but sadly that just means "visible within the organization". From the outside not much is shown:

Yes, it's a limitation of Github to not shown the teams outside the organization.

We can add comments in the CODEOWNERS file that mirrors the team members. F.ex.:

# ggml-org/team-abc : member1, member2, ...

I have added comments as suggested.
