Subject: [PATCH] chore(rds): removed unreleased aurora postgres 16.3 cluster
 engine. (#30296)

### Issue #:
Closes #30254.

### Reason for this change
PR https://github.com/aws/aws-cdk/pull/30242 added Aurora Postgres version `16.3`, which is not yet released.

### Description of changes
This PR removes the yet unreleased version of Aurora Postgres version `16.3` that was added in PR https://github.com/aws/aws-cdk/pull/30242.

Running `aws rds describe-db-engine-versions --engine aurora-postgresql --query '*[].[EngineVersion]' --output text` via AWS CLI does not list `16.3` version yet.
