Unable to assign IPv6 CID block to default VPC

[ewbankkit]

I am unable to assign an IPv6 CIDR block to a region's default VPC:

resource "aws_default_vpc" "d" {
  assign_generated_ipv6_cidr_block = true
}

$ terraform plan
1 error(s) occurred:

* aws_default_vpc.d: "assign_generated_ipv6_cidr_block": this field cannot be set

An IPv6 CIDR block can be assigned via the AWS CLI or console.

This is because the aws_default_vpc.assign_generated_ipv6_cidr_block attribute is marked as "output-only": https://github.com/terraform-providers/terraform-provider-aws/blob/4e06a36422cac377c9c4f5fbd573954b857ef38f/aws/resource_aws_default_vpc.go#L28-L32

Closing in favor of #4959.
