RDS - aurora-postgresql dropped version 14.6?

Question

I've had a fresh Aurora Postgres cluster running with version 14.6 for a few weeks now.

Today I was doing updates to my general AWS infrastructure and noticed Terraform started returning errors when fetching engine version information for 14.6
```
data "aws_rds_engine_version" "postgresql" {
  engine  = "aurora-postgresql"
  version = "14.6"
}

Error: no RDS engine versions found
│ 
│   with data.aws_rds_engine_version.postgresql,
```

Confused, I checked Postgres and AWS management console and the versions are indeed 14.6 still
```
postgres=> select version();
                                                   version
-------------------------------------------------------------------------------------------------------------
 PostgreSQL 14.6 on aarch64-unknown-linux-gnu, compiled by aarch64-unknown-linux-gnu-gcc (GCC) 7.4.0, 64-bit
```

When checking for available versions with `describe-db-engine-versions`, 14.6 has disappeared (14.5 being latest).
```
aws rds describe-db-engine-versions --region eu-west-1 --engine aurora-postgresql --engine-version 14
```

Did I miss something about 14.6 being dropped or is this a bug?
