Bump pg versions 14.15, 15.10, 16.6 (#7829)

Bump PG versions to the latest minors 14.15, 15.10, 16.6

There is a libpq symlink issue when the images are built remotely
https://github.com/citusdata/citus/actions/runs/12583502447/job/35071296238
Hence, we use the commit sha of a local build of the images, pushed.
This is temporary, until we find the underlying cause of the symlink
issue.
