Examples leveraging submodules have relative paths to directories inside of the project instead of referencing Terraform Registry Module path

[thogarty]

The module source is relative in the examples.

E.g.

module "create_virtual_device_2_azure_connection" {
  source = "../../modules/virtual-device-connection"
  ...
}

Instead of being a reference to the published module in the Terraform Registry:

module "create_virtual_device_2_azure_connection" {
  source  = "equinix/fabric/equinix//modules/virtual-device-connection"
  version = "0.18.0"
  ...
}

This means that we are not showing customers how to leverage the module fully and are omitting an important step.
