Querying `minimum_gas_price`

[daniel-savu]

Hi, I'm trying to query the minimum_gas_price configured by the node, as added in https://github.com/cosmos/cosmos-sdk/pull/13485 at /cosmos/base/node/v1beta1/config.

I noticed the protobuf methods are already in place here: https://github.com/cosmos/cosmos-rust/blob/main/cosmos-sdk-proto/src/prost/cosmos-sdk/cosmos.base.node.v1beta1.tonic.rs

However it doesn't look like this is exposed in cosmos-sdk-proto. Is this rpc call currently supported in cosmrs?
