feat: Create Snaps API documentation from generated schema

[Mrtenz]

Description

This adds a Docusaurus plugin for dynamically generating Snaps API documentation from a schema file. The schema file will be generated automatically based on the implementations in MetaMask/snaps. This allows for easier maintenance of the documentation, as some methods have become quite outdated currently.

The plugin works by fetching the schema file, and writing a new MDX file to disk for each JSON-RPC method. I've considered a similar approach to the Wallet API documentation, but it had several drawbacks, like needing to hack the sidebar to show the dynamic items. By generating the MDX files before running Docusaurus, @docusaurus/plugin-content-docs will just pick it up as any other documentation page.
