rpc: the grpc proto file where the API are generated need to be last tagged version

[vincenzopalazzo]

The actual grpc API are generated in the current version of master, and the listtransaction want an additional filed, on my node I receive the following error

Another exception was thrown: Exception: gRPC Error (code: 2, codeName: UNKNOWN, message: Error calling method ListTransactions: RpcError { code: None, message: "Malformed response from lightningd: missing field `amount_msat`" },
details: [], rawResponse: null, trailers: {date: Sun, 26 Jun 2022 17:00:06 GMT})

We need to generate the GRPC file from the last release https://github.com/ElementsProject/lightning/releases

P.S: You need to check out the git tag!
