indy.error.CommonInvalidState in demo caused by outdated TestNet genesis URL

[jkrupicka]

When completing this Hyperledger Aries Workshop, I encountered a problem with starting up the agents for the demo. In the demo directory, I run docker-compose -f docker-compose.alice-bob.yml up --build and Alice and Bob both start up, but they both shut down after indy.error.CommonInvalidState. I believe that this Discord message cites the same problem. The stack trace is below.

I determined that the problem is with the Indicio TestNet Genesis URL in demo/configs/alice.yml and demo/configs/bob.yml. The URL currently is https://raw.githubusercontent.com/Indicio-tech/indicio-network/master/genesis_files/pool_transactions_testnet_genesis, but I believe that Indicio has switched their naming convention from "master" to "main." Changing the URL to https://raw.githubusercontent.com/Indicio-tech/indicio-network/main/genesis_files/pool_transactions_testnet_genesis fixes the issue.

I will also submit a PR with this fix, but given that this is my first PR for aries-acapy-plugin-toolbox, I wanted to submit an issue with more information to make sure I'm not missing anything.
