[FEATURE]: Previews of templates

[cadop]

Description

There are a bunch of kit templates, and variations of those templates. I can see what they look like by navigating into the readme for each one, and then scrolling through that readme, but it's hard to visually/mentally track the differences.

Use Case or Scenarios

It is easier to narrow down the template to start exploring first, and understand the variations.

Possible Implementation Ideas

Similar to warp, that has main categories and sub-samples (no pun intended)

Additional Context or Recommendations

Please

This is a good idea. As the KAT repository continues to evolve, an aesthetic/content update of the docs is likely, and something like this would be a good addition.
