Add trashed event for SoftDeleted models

[calebdw]

Hello!

Thanks for such a great package! I'm in the middle of converting our custom auditing solution to use this package.

It seems that trashed models are shown as deleted in the audits, but this is confusing as the actual forceDelete action is also shown as deleted. Essentially, there's no way by looking at the table if a model uses soft deletes and if the record was actually deleted or just trashed

I think it would be great to instead have soft deleted models show the trashed state instead.

For example, the following code would produce these events in the audits:

$m = ModelWithSoftDeletes::factory()->create(); // created
$m->delete(); // trashed
$m->restore(); // restored
$m->forceDelete(); // deleted

Thanks!

Feel free to make a PR, some member will review it and hopefully merge it.
but it sounds like a breaking change, because the delete event is arready being used on SoftDeleted models,
if someone waits for the delete event and suddenly gets trashed event?

Both the deleted and trashed events are fired for soft deleted models, same for deleted and forceDeleted
