[FEATURE] Have example prompts as part of samples

Is your feature request related to a problem? Please describe.
Not all the examples are obvious about what their intended use is or the type of input that they work best with. It'd be great if the examples could have some example prompts to fill the textbox with (or other inputs) as examples to help best demonstrate the use-cases for certain scenarios.

i.e. the "Content Moderation" example just has an empty textbox and says enter content, but what type of content? Is it best on longer paragraphs of responses or just a sentence? Having some practical examples would go a long way to help me as a developer best understand where to use this.

Describe the solution you'd like
Button or dropdown option near prompt inputs to select and fill-in a pre-existing example input/prompt.

Describe alternatives you've considered
More information/documentation surrounding individual samples.

Additional context

What should I put here? What's a best example to showcase the strength of this feature?

Related to a few other issues here like #105 and #473, but still different as about showing the functionality of the feature vs. various implementation details.
