feat: restore TimescaleDB extension support for PostgreSQL 17

restores TimescaleDB support for PostgreSQL 17 by:

1. Adding TimescaleDB 2.23.0 to versions.json with PG 15 & 17 support
2. Removing timescaledb from filtered extensions list for PG 17
3. Removing sed commands that stripped timescaledb from Dockerfile-17
4. Updating migration test to support PG versions up to 18
5. Keeping timescaledb in shared_preload_libraries (postgresql.conf.j2)

TimescaleDB 2.23.0 is the first version to officially support PostgreSQL 17.
Previously filtered in PR supabase#1321, now restored following contribution guidelines.
