[ENHANCEMENT] No Gherkin DrillDown

[kivancbayram]

Problem
When clicked on Gherkin steps, IDE does not forward us to the related method/code unlike Cucumber.

Suggested Solution
Clicking on Gherkin steps user is forwarded to related code in the IDE.

Reproduce Steps

1. Open a .feature extended file in an IDE (ex: VsCode)
2. Click (Ctrl + Click) one of the Scenario steps (ex: Given I log in to Facebook)
3. Check if the IDE screen switches to the related file/code

I have added a pull request: #16
to add the functionality.

[RachmatKaligis]

created a separate extension to enable the functionality:

I tried the plugin, it is working very well as expected, the issue can be closed.
