Fixes #5565, by using tags instead of trying to string match on a `MessageData`. This ends up reverting some unwanted test output changes from #4781 too. This changes `isMaxRecDepth` for good measure too. This was a regression in Lean 4.11.0, so may be worth backporting to 4.12.x, if not also 4.11.x.
