Update the default region mapping based on the latest changes in [AWS Regions and Endpoints document](https://docs.aws.amazon.com/general/latest/gr/rande.html#s3_region)

The default region mapping can be overridden by using `--v4-region-map` parameter (more info in the [s3 plugin docs](https://docs.trafficserver.apache.org/en/8.0.x/admin-guide/plugins/s3_auth.en.html#aws-authentication-version-4)).
