Expand supported regions

Tested with the following:

    #!/bin/bash

    regions="us-east-1 us-east-2 us-west-1 us-west-2 ca-central-1 ca-west-1 us-gov-east-1 us-gov-west-1 mx-central-1 sa-east-1 eu-west-1 eu-west-2 eu-west-3 eu-central-1 eu-north-1 eu-south-1 eu-south-2 eu-central-2 il-central-1 me-south-1 me-central-1 af-south-1 ap-northeast-1 ap-northeast-2 ap-northeast-3 ap-southeast-1 ap-southeast-2 ap-southeast-3 ap-southeast-4 ap-east-1 ap-south-1 ap-south-2 ap-southeast-5 ap-southeast-7 cn-north-1 cn-northwest-1"

    export AWS_PAGER=
    for i in ${regions}; do
        out=$(aws ec2 describe-instance-type-offerings --location-type region --filters "Name=instance-type,Values=g5.2xlarge" --region "${i}" 2>&1)
        ret=$?
        if [ $ret -eq 0 ]; then
          echo -n "${i} "
        fi
    done
    echo ""

Got:
