README: Gherkin grammar diagram (AST) is missing Gherkin v6 changes (Rules, ...)

[jenisys]

👓 What did you see?

The Gherkin grammar diagram does not contain the changes that were made since Gherkin v6:

• Rule keyword/entity is missing in the diagram

SEE ALSO:

• Gherkin grammar diagram
• Gherkin grammar: gherkin.berp
• docs.cucumber.io: Gherkin Reference -- Keywords

✅ What did you expect to see?

• Rule keyword/entity should be shown in diagram

TO BE CLARIFIED: Should aliases be shown ?!?

• Example: Alias for Scenario
• Scenario Template: Alias for Scenario Outline
• Scenarios: Alias for Examples table(s) in Scenario Outline

📦 Which tool/library version are you using?

I just inspected the Gherkin diagram and compared it with the gherkin.berp grammar.

🔬 How could we reproduce it?

Steps to reproduce the behavior:

1. Compare Gherkin grammar diagram with gherkin.berp and/or Gherkin description in docs.cucumber.io: Gherkin Reference page
2. Gherkin grammar diagram does not contain Rule entity
