Reminder to fix return type of resolver query

[dev8723]

Return type is definitely not all SimulateResponse here

#[derive(QueryResponses)]
#[cw_serde]
pub enum QueryMsg {
    #[returns(SimulateResponse)]
    SimulateQuery(SimulateQueryMsg),
    #[returns(SimulateResponse)]
    QueryValidateJobCreation(QueryValidateJobCreationMsg),
    #[returns(SimulateResponse)]
    QueryHydrateVars(QueryHydrateVarsMsg),
    #[returns(SimulateResponse)]
    QueryResolveCondition(QueryResolveConditionMsg),
    #[returns(SimulateResponse)]
    QueryApplyVarFn(QueryApplyVarFnMsg),
    #[returns(SimulateResponse)]
    QueryHydrateMsgs(QueryHydrateMsgsMsg),
}

#[cw_serde]
pub struct SimulateResponse {
    pub response: String,
}

some of them are returning string, some returning Vec<CosmosMsg>, setting it incorrectly might not break the query, but i think it will mess up the generated json schema and typescript client.
