Updated model without creating a revision

[SergkeiM]

Sometimes when your work with unpublished record (Draft) you may need to not create a revision for it.

You can write in your model::

public function withoutRevision(): static
    {
        $this->shouldCreateRevision = false;

        return $this;
    }

I've added a PR if this is needed to someone else as well: #15

Can be closed #15 was merged thank you @oddvalue for this package saved me ton of time.
