Add JSON schemas for Minecraft assets

[TheOnlyTails]

The Problem

Writing JSON is hard and annoying, especially when you have no way to verify if you've entered the right fields. IntelliJ has no built-in way to automatically guess the structure of the JSON.

The Solution

JSON Schemas! They're another special JSON file that that once added to IntelliJ with a file/path pattern (to determine which files to apply it too), will add auto-completion of fields, warnings for invalid values, and more.

(If needed, I have some experience writing them so I can make the schemas myself)

So, for me, adding JSON schemas in the plugin is useless, because Intellij Idea support the Schema Store API. My PR is closed because I prefers to add schema for the schemastore insteadof the plugin.

I think we can keep this issue open for those who would like to open others on the same topic but in my opinion, adding a feature to the plugin for that is useless.
