* TF provider >= 4.54.0 now returns `rsa_encrypted_key` for
`google_compute_disk.disks["attached-disk"]` (see
hashicorp/terraform-provider-google#4448)
* Add this field to expected model to fix test assertion failure
* Update required TF provider to 4.55.0 (latest) since the assertion
will now fail with <4.54.0, which do not return `rsa_encrypted_key`
* Updated the whole repo on advice from @ludoo
