Fix null requested_reviewer from API (#31773)

If the assign the pull request review to a team, it did not show the
members of the team in the "requested_reviewers" field, so the field was
null. As a solution, I added the team members to the array.

fix #31764

(cherry picked from commit 94cca8846e7d62c8a295d70c8199d706dfa60e5c)
