Please prefer not to revert this change. Any tests that fail are release blockers and need to be approved and urgently fixed forward. Dart 3.2 has already been cut and the version number must be updated. It is acceptable for rolls to be blocked until the release blockers have been resolved as P0 issues. Remove needless version number comment from experimental_features to remove duplicated information and simplify version updates. Update dartdoc to a version that supports 3.3.
