Don't show Topic Cards' style in the Suggested topics

Topic Cards

I have made a PR to this theme component with two additions: Feature: Suggested topics switch Adds the setting Show for suggested topics Makes use of topic cards for suggested topics optional (as described in this feature request) Feature: Limit to categories Adds the setting Show on categories If non-empty, uses topic cards on selected categories only.

Merged in today.
