Add support for asterisk (`*`)

[RemiBardon]

Could you add support for asterisk (*)?

According to Gherkin Reference - Cucumber Documentation:

*

Gherkin also supports using an asterisk (*) in place of any of the normal step keywords. This can be helpful when you have some steps that are effectively a list of things, so you can express it more like bullet points where otherwise the natural language of And etc might not read so elegantly.

For example:

Scenario: All done
  Given I am out shopping
  And I have eggs
  And I have milk
  And I have butter
  When I check my list
  Then I don't need anything

Could be expressed as:

Scenario: All done
  Given I am out shopping
  * I have eggs
  * I have milk
  * I have butter
  When I check my list
  Then I don't need anything
