Register ProjectDeletion events for gson serialization

ProjectDeletion events were not registered event types.

This caused failures when EventGson tried to serialize/deserialize
objects having those events as field, Throwing the JsonParseException:

```
Unknown event type: project-deletion-replication-scheduled
```

Register ProjectDeletion event types, similarly to what already done for
Ref replication events (RefReplicatedEvent, RefReplicationDoneEvent,
RefReplicationScheduledEvent).

Bug: Issue 14628
