JSON Schemas for LivelyProperties and LivelyInfo

[dejohansson]

Is your feature request related to a problem? Please describe.

It can be frustrating to define LivelyProperties.json and LivelyInfo.json without any validation or IntelliSense pointing you in the right direction.

Describe the solution you'd like

1. Define JSON Schemas for LivelyProperties.json and/or LivelyInfo.json.
2. (Optional) Add entries for the schemas in the JSON Schema Store.

Additional context
IntelliSense example using a draft JSON Schema.

Are you interested in implementing it?

(Ignore LivelyInfo.json as its use is internal only with the argument field being the only exception.)

Are you interested in implementing it?

Yes, I would like to have a go at implementing it.

So far I have been using this wiki page to figure out the schema definition. Which part of the source code should I start looking at if I want to reverse engineer the types and constraints for LivelyProperties.json?

[rocksdanister]

The wiki is up-to-date and complete, there is an upcoming change but that only affects the receiving JS code so no issue.

This is the source, controls are wrappers around native WinUI 3 controls.
