Fix syntax broken in #604

Description

This fixes a cut/paste error introduced in #604 in the standard catalog that caused the displayStyle to be followed by this:

            "type": "string",
            "description": "The display style of the component.",
            "enum": [
              "checkbox",
              "chips"
            ]

Which is incorrect (since display style already included those, and we don't want a parameter named "type" or "description"). It's just a failed replacement.

I also formatted the JSON document using the "Prettier" rules.
