Suggestion cards in nested lists

[gadenbuie]

We have in the past encouraged suggestion lists inside of nested lists (e.g. querychat) and might want to support suggestion cards in this context, e.g.

Here are a few ideas to get you started:

* **Analyze the data**
  * <span class="suggestion">What is the average body mass of the penguins?</span>
  * <span class="suggestion">How many species are in this dataset?</span>
* **Create visualizations**
  * <span class="suggestion">Show me a bar chart of penguin counts by species.</span>
  * <span class="suggestion">Plot a scatter plot of bill length vs. bill depth.</span>
* **Filter and sort records**
  * <span class="suggestion">Show me all penguins from the Biscoe island.</span>
  * <span class="suggestion">Sort the penguins by flipper length, largest to smallest.</span>
