[E2E] run a second e2e chain by reusing the current setup

[p0mvn]

Background

Currently, our e2e tests only spin up one chain. We might want to have another chain enabled so that we can test IBC.

We can do so by doing the following steps:

1. Add chain b to the suite
2. Update the network to have both chains in its name:

• This is just a cosmetic change

3. Add the following lines to initialize the chain
4. Initialize different values for these parameters on the second chain

• e.g set osmoBalance = 500000000000
• This is done so that we can query them on a different chain and ensure that they are set correctly

6. Implement a similar test query for the new chain:
   E.g. assert that osmoBalance = 500000000000

Acceptance Criteria

• chain b starts successfully
• new test balances query passes where it validates different balances from chainA
