insufficient timeout for direct connect virtual interface

[displague]

It is very common to hit the default 10m creation timeout:

module.equinix-fabric-connection-aws.aws_dx_private_virtual_interface.this[0]: Still creating... [10m0s elapsed]
╷
│ Error: error waiting for Direct Connect virtual interface (...-...) to become available: timeout while waiting for state to become 'available, down' (last state: 'pending', timeout: 10m0s)
│

│   55: resource "aws_dx_private_virtual_interface" "this" {

╵

A few minutes later seems to be sufficient.
