Add edition checks for some tests that had divergent output In order to expose edition dependent divergences in some tests in the test suite, add explicit `edition` annotations. Some of these tests might require additional work to avoid the divergences, as they might have been unintentional. These are not exhaustive changes, purely opportunistic while looking at something else. 2025-06-09 17:52:41 +00:00			`//@revisions: edition2015 edition2024`
