I created a clean 14.3 server with everything default on server creation. Ran the setup script did the test and again I was able to query the data successfully. I then decided to create a clean 15.3 server with everything default. Ran the setup script did the test and was not able to query the data.
Interestingly enough I contacted AWS and presented the same issue to them and they informed me that they could duplicate my exact issue, and said yes there was a functionality change from 14 to 15, but they did not say if the change was something they did with their RDS Postgres or was it something changed in the underlying Postgres build.

Yes it would if sten_schema would inherit from rds_superuser. But it
cannot inherit privileges from rds_superuser (indrect membership through
object_creator) because object_creator was created with NOINHERIT. And
INHERIT applies to direct memberships only.
