Merge rust-bitcoin#229: feat(run-bitcoind): add run as alias for start

83bf49d feat(run-bitcoind): add run as alias for start (oyindamola oladapo)

Pull request description:

  ### Summary

  This PR adds support for `run-bitcoind run` as an alias for `run-bitcoind start`.

  ### Changes

  - Updated the command parser to treat `run` the same as `start`, without changing existing behavior.

  This allows users to invoke:
  ```bash
  ./run-bitcoind.sh run [VERSION_ALIAS]

  ```

  closes rust-bitcoin#226
