Commit 16fdb6ca5e introduced `timescaledb_experimental.policies` view to expose the Continuous Aggregate policies but the current JOINS over our catalog are not accurate. Fixed it by properly JOIN the underlying catalog tables to expose the correct information without duplicates about the Continuous Aggregate policies. Fixes #5492
