Feature: Variable (from Examples section) interpolation inside docstrings.

[metacoma]

hello, thank you for developing pytest-bdd-ng'

I am using the following approach to prepare and send a cloud event:

   Scenario: Send ping directly to function <endpoint>                                                                                                                    
      When God creates a new cloudevent                                                                                                                                    
       And God starts reading message from NATS topic ">"                                                                                                                                                                                                          
        And sets cloudevent header "ce-source" to "org.mindwm.<username>.<host>.clipboard"                                                                                 
        And sets cloudevent header "traceparent" to "<traceparent>"                                                                                                        
        And sends cloudevent to "<endpoint>"

If there was way to use "variables" from the Examples section inside the docstring, my scenario description would look like this.

   Scenario: Send cloudevent directly to knative function <endpoint>                                                                                                                    
      When God creates a new cloudevent

I am not sure how complex this would be to implement, but I think it would be very convenient.
