Add more steps context support (#887)
* feat: add more steps context support

- Add step outcome
- Remove step success in favour of conclusion

* feat: add conclusion and outcome steps context tests

Add corresponding tests and extend pkg/runner/expression.go vmSteps() to
handle steps context conclusion and outcome iota as strings.
