Assert: Remove deprecation warning from assert.push()

Cherry-picks eaa0dbe (3.0.0-dev)

> This is still used by numerous plugins that have no other reason to
> break [in QUnit 3.0.0]. It's trivial to map to the new method
> and requires no maintenance or increased complexity, and we're not
> under any size constraints. Let's keep it around.
