fix(proto): update DomainType::Proto for ClientState/ConsensusState

[noot]

Found this bug while testing the IBC implementation with Hermes. Previously it was writing an Any type to state at the client_state/consensus_state storage locations, but the type Hermes was expecting was the ibc_proto ClientState/ConsensusState. This resulted in a proto decoding error in these locations:
https://github.com/informalsystems/hermes/blob/master/crates/relayer/src/client_state.rs#L127
https://github.com/informalsystems/hermes/blob/master/crates/relayer/src/consensus_state.rs#L59

These are called in the Endpoint query_client_state/query_consensus_state methods (for example here https://github.com/informalsystems/hermes/blob/b98ca86991fc1cc6d3f6c595918251a34eb6f1db/crates/relayer/src/chain/cosmos.rs#L1238)

specifically the error I got from Hermes was Error::decode_raw_client_state:

ERROR failed while querying for client 07-tendermint-0 on chain id astria: other error: error decoding raw client state: error decoding buffer into message: failed to decode Protobuf message: Fraction.numerator: ClientState.trust_level: invalid wire type: LengthDelimited (expected Varint)

I can give more details on how I was running everything if needed!

also linted the protos cause CI complained 😭

LGTM! Thanks for the find.
