Aws::EC2::RouteTable#create_route raises on creating IPv6 route, after successfull API call.

[oskgu360]

Describe the bug

Creating an IPv6 route on a route table fails internally in client cause it expects a IPv4 CIDR to be provided, but EC2 api expects only the IPv6 argument, so API call is made successfully before raising internal ArgumentError.

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

Expected is that https://github.com/aws/aws-sdk-ruby/blob/version-3/gems/aws-sdk-ec2/lib/aws-sdk-ec2/route_table.rb#L299-L303 would pass the destination_ipv_6_cidr_block to the Route class, which in its turn should be able to handle that argument instead of the IPv4 correspondent (destination_cidr_block).

Current Behavior

Currenty raises on https://github.com/aws/aws-sdk-ruby/blob/version-3/gems/aws-sdk-ec2/lib/aws-sdk-ec2/route.rb#L413 due to missing the IPv4 CIDR argument.

Reproduction Steps

Create a VPC, an internet gateway and route table on that VPC. Try to add any IPv6 route to that internet gateway on the routing table via the Aws::EC2::RouteTable#create_route method.

Thanks for opening an issue. Unfortunately the resource models are not maintained and soft deprecated. Can you try creating your route tables using a typical Client call instead?

Ah okay, thanks :)
