Projects may assign external (non-committer) collaborators the triage role for their repository.
The triage role allows people to assign, edit, and close issues and pull requests, without giving them write access to the code.

I add active contributors to the collaborators list.

Why are the changes needed?

It's convenient for the active contributors to manage issues.

Does this PR introduce any user-facing change?

No

How was this patch tested?

No
