## Issue Addressed
Resolves https://github.com/sigp/lighthouse/issues/2763
## Proposed Changes
- Add a workflow which tests that local testnet starts successfully
- Added `set` option into the scripts in order to fail fast so that we can notice errors during starting local testnet.
- Fix errors on MacOS
- The redirect `&>>` is supported since bash v4 but the version bundled in macOS(11.6.1) is v3. a54f119c9b
