bug(`permit2_signature_transfer`): example fails to run

Currently fails with:

```
Sent approval: 0x93426765c406ba149df94b52df30b415bc812b7d384dbcaafb9a389a4eec3555
Error: server returned an error response: error code 3: execution reverted, data: "0x"
```

Does not appear to be a regression as it also appears on main prior to the Alloy bump

I think this is expected to succeed
