Mention Drupal on the mermaid integrations page

This is a great idea maxilein. I am going to move this issue to the mermaid diagram field module and then submit it as you suggest.

I created a https://github.com/mermaid-js/mermaid/pull/5389 to add Drupal and the Mermaid Diagram field module to the list.

Automatically closed - issue fixed for 2 weeks with no activity.
