error[E0004]: non-exhaustive patterns: `Stable2` and `_` not covered

Point at uncovered variants in enum definition in `note` instead of a `span_label` This makes the order of the output always consistent: 1. Place of the `match` missing arms 2. The `enum` definition span 3. The structured suggestion to add a fallthrough arm
