close#25833
Currently, the information for "requested_reviewers" is only included in
the webhook event for reviews. I would like to suggest adding this
information to the webhook event for "PullRequest comment" as well, as
they both pertain to the "PullRequest" event.
Also, The reviewer information for the Pull Request is not displayed
when it is approved or rejected.
