Enhance visual storytelling with components

[jyecusch]

There are several areas of the nitric documentation that would be enhanced through visual aides (providers, deployment, messaging, etc.)

We'd like to add the following components to the docs site, so they can be used primarily through configuration:

• Animated beams (uni-directional, bi-direction, multi-input/out)
• File tree
• Icon cloud (this may only be needed on the homepage)
• Compare (left/right comparisons - e.g. comparing two code examples side by side)
