Create a run.sh for commit-boost

[OisinKyne]

🎯 Problem to be solved

In all other VCs etc, we override the docker cmd with a script, that parses the .env vars and passes them to the real runtime command. This allows us to prep config or keys, or other things.

For commit-boost, we have to copy a command manually.

We can skip this user friction by writing a script that prepares the right config.yaml. we could also make it work with .env vars and selective volume mounts. (ie. mount "./commit-boost/config.sample.${NETWORK:-mainnet}.toml:/correct_mount_path/config.toml" if that is tested and works).

🧪 Tests

• Works in local docker-compose
• Has a attested on a testnet at least once
