Remove non-pg17 bitnami images from tests

Bitnami removed support for LTS branches. For us this means only
PG17 will get postgres version updates. So this PR removes the
images for previous branches from CI test.

bitnami/containers#75671

This patch also adds missing timescaledb-ha:pg17 image to the tests.
