Use Field::RichText type for ActionText has_rich_text associations

[smartygus]

• detects ActionText rich text associations based on class name and attribution name and if it's a match, returns the built-in Field::RichText type
  Closes Dashboard Generator doesn't recognise ActionText Rich Text fields #2925

Thank you!

(I tested it locally, and it'll take a rich_text_content — like what's in the Rails guides — and set to use the right field.)

Cool, yeah that was my intention 👍
It was basically a hiccup in my first-run experience with administrate, cos my app was using Action Text a fair bit, and it seemed like a relatively small fix, so I figured I may as well contribute!

Thanks for the review, the tweaks, and the merge 😃
