Add "Pin Component Format" to README.md

[brentru]

The README.md has the pin component format as a TODO item.

The format used by pin components is reflected by the pin/schema.json file in this repository.

You may either (simple) link to the schema from within the README file, or (better) explain the schema in the README as a table/visually as you best see fit.

Hey👋 @brentru, Could you please share an example(docs maybe) if possible regarding the way I should explain the schema.

[brentru]

@VividhPandey003 I'd start by listing each item from properties and their description.
