This PR replaces the proof of the simplification lemma `Nat.zero_mod` with `rfl` since it is, by design, a definitional equality. This solves an issue whereby the lemma could not be used by the simplifier when in 'dsimp' mode. Closes #9389 --------- Co-authored-by: Joachim Breitner <mail@joachim-breitner.de>
