Include PATCH rule for events in manager-role

During high custom resource count / low interval tests, I was greated
with a `cannot patch resource "events"` message. This happened due to
event compaction, where it will perform a patch instead of a create.
By giving the role the permission to do so this should no longer pose
a problem.
