samples: Update Data Catalog samples to client library V1 (#2604)

With release of V1 library, we must update the samples to instruct users to use the supported version.

- [ x] Tests pass
- [ n/a] Appropriate changes to README are included in PR
- [ n/a] API's need to be enabled to test (tell us)
- [ n/a] Environment Variables need to be set (ask us to set them)
