fix: fixed QueryAllPairsValConAddrByConsumerChainID output formatting (backport #1722)

[mergify]

Description

Fixes the issue described here: #1251 (comment)

Converts QueryAllPairsValConAddrByConsumerChainID output to consumer addresses, so instead of raw bytes in gRPC/REST response we now have this:

I patched my Gaia node with this: https://api.cosmos.quokkastake.io/interchain_security/ccv/provider/consumer_chain_id?chain_id=neutron-1, seems to work more correct, also tested it with gRPC and it also works.
