🧑‍💻 Output path to feature file and source for steps

Problem:
  Working with BDD tests can be challenging in large repositories
  because it is difficult to find the implementation of steps. Patterns
  of text substitution and multi-line strings make simple greps for step
  definitions insufficient.

Solution:
  Rather than outputting either the step location or the feature file
  location, we will instead output the feature file location and
  optionally the step definition location if available (uses $Given,
  $When, $Then)
