fix: remove `project.approvals.set_approvals()` method

The `project.approvals.set_approvals()` method used the
`/projects/:id/approvers` end point. That end point was removed from
GitLab in the 13.11 release, on 2-Apr-2021 in commit
27dc2f2fe81249bbdc25f7bd8fe799752aac05e6 via merge commit
e482597a8cf1bae8e27abd6774b684fb90491835. It was deprecated on
19-Aug-2019.
