use `--json` flag for better output parsing

Feature request

act has an option to enable json output. Using json will provide much easier output parsing than the current regex based string parsing. This will also significantly reduce maintenance complexity.

Additional context

The output-parser is a pluggable module, which make it easy for us to add another output parser without any breaking changes

Oh, brilliant. Don’t know how I missed that. I can try to take a look this weekend.
