incorrect AWSPhone validation for +614839 prefix.

Valid mobile Australian mobile phone numbers starting with: +614839..... aren't supported in appsync, fails validation.

We have valid AU mobile phone number data from a phone system, real numbers that are sync'd into dynamodb.

Reproduce by putting a value +61 483 911 111 into your data set. Dynamodb in our case.

Query error response via:

AppSync response: "message": "Can't serialize value (path/to/phoneNumber) : Unable to serialize +614839..... as a valid phone number.

* try a correct: +61 483 111 111 and see no errors.

Perhaps similar to issue: #211

Reproduce the AppSync validation error with +61 483 911 111 and compare it with the accepted +61 483 111 111 case. Read related issue #211 for context, then determine where the AWSPhone validation behavior is documented or configured. Done means valid Australian numbers with the +614839 prefix are accepted without a serialization error.
