relayer: try multiple cosmos testnet chains

In debugging relayer support, let's set aside Penumbra chains entirely,
and focus on what should be a well-supported use case for the relayer:
one cosmos testnet to another cosmos testnet. Unfortunately, I don't
have any of these configs working yet, so they're commented out in the
`run-relayer` script, for now.

+block in the `./configure-relayer` script for some example paths between chains
