feat(ingest/unity): Support specifying catalogs directly; pass env correctly (#9110)

docs/how/updating-datahub.md

@@ -68,6 +68,9 @@ qualified dataset name, i.e. `<project_name>.<dataset_name>`. We attempt to supp
 pattern format by prepending `.*\\.` to dataset patterns lacking a period, so in most cases this
 should not cause any issues. However, if you have a complex dataset pattern, we recommend you
 manually convert it to the fully qualified format to avoid any potential issues.
+- #9110 - The Unity Catalog source will now generate urns based on `env` properly. If you have
+been setting `env` in your recipe to something besides `PROD`, we will now generate urns
+with that new env variable, invalidating your existing urns.
