feat: handle VRF Gateways in "metal gateway list"

[displague]

Adds metal gateway list support for VRF Gateways.

Why is this needed?

$ metal gateway get
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0xad902e]

My default project ID was old (no longer exists).

Updated to a valid one:

go run ./cmd/metal/ gateways list -p $METAL_PROJECT_ID

Output with a VRF and non-VRF Gateway:

Does this really count as getting rid of the if block within the for loop?
