tag learnr tutorials with extra metadata?

[kevinushey]

As part of the Tutorial pane work in the RStudio IDE, I'd like to make a landing page for all discovered tutorials provided by any installed packages. It currently looks like this:

The presentation is currently a bit bare. I wonder if there is some other relevant metadata we could include for a particular tutorial, e.g.

• A short, single-paragraph description? [description]
• The R package(s), if any, one might learn about in this tutorial? [packages]

The format I'm currently imagining would be something like:

Data Basics [ex-data-basics]

Learn about the base data types in R. Explore R's data frames, and learn how to interact with data frames and their columns using dplyr.

Packages: dplyr, tibble

All the relevant data here could be included as part of the YAML header.

@kevinushey any way to render a thumbnail of the tutorial in the pane?

Not currently, but we could allow for something like icon.png if that would be helpful.

@kevinushey that would be great. Though, might need to enforce image size (storage + display).
