Data Catalog v1beta1 API: Massive Breaking Changes & Rollback

Modified API Methods (36):

The datacatalog.v1beta1 API has experienced a near-complete removal of its core functionality. All methods under entries, projects.locations.entryGroups, and projects.locations.tagTemplates have been removed, including critical operations like lookup, create, delete, get, list, patch, setIamPolicy, testIamPermissions, and rename. Furthermore, key schemas such as GoogleCloudDatacatalogV1beta1Entry, GoogleCloudDatacatalogV1beta1EntryGroup, GoogleCloudDatacatalogV1beta1Tag, and GoogleCloudDatacatalogV1beta1TagTemplate have had most, if not all, of their properties removed. This change effectively deprecates the entire v1beta1 API surface. Developers currently using v1beta1 must migrate to a stable API version immediately. This also rolls back the recent addition of NODE and EDGE entry types, as the Entry schema and its type field are no longer available in this version.
