Support alternate step parsers (re in particular)

[gabeseltzer]

In short, the Two-way step navigation doesn't work with the re step parameter parser.

My team tried out the re step parser (see Behave Docs). I'm able to run my tests as expected, but if I look at the .feature file, the steps that make use of the re parser are shown in red and can't be matched to their step definitions (ie, pressing F12 doesn't take me to the definitions).

# myfeature.feature
Feature: my feature
    Scenario: check the camera
         Given the camera is enabled
         Then the camera is enabled

# steps.py
use_step_matcher("re")
@given("the camera is (?P<status>enabled|disabled)")
def given_camera_status(context: Context, status: str) -> None:
    # Do some stuff

@then("the camera is (?P<status>enabled|disabled|disconnected)")
def then_camera_status(context: Context, status: str) -> None:
    # Do some stuff

Describe the solution you'd like
I'd love to be able to use Two-way step navigation with my regex parameter steps.
