This PR fixes the `revert` tactic so that it creates a `syntheticOpaque` metavariable as the new goal, instead of a `natural` metavariable I reported it on [Zulip](https://leanprover.zulipchat.com/#narrow/channel/270676-lean4/topic/.60revert.60.20gives.20natural.20metavariable.20goal/near/483388096)
