Given, When, Then autocomplete

[mazfish]

Hi, and thx for this lib.

You note "Given, When, Then, And and * are all synonyms, and exist only to make your code more readable." but there's issues with IDE gherkin/cucumber autocompletion plugins which use "Given", "When", "Then" keywords in steps definitions.
Ex.: vscode + cucumber autocomplete

To fix it i use a "stucumber wrapper" which defines these 3 ones, wrapping cucumber.defineRule().

You could propose its like (or otherwise):
import { cucumber, Given, When, Then } from 'stucumber';

It could be done in stucumber but in gherkin-jest as well.
import { cucumber, Given, When, Then } from 'gherkin-jest';
