Unified config object with type information

[silvester-pari]

Currently we use lots of separate config objects in globalThis, which makes it hard to provide the developer guidance/feedback about the possible options. It would probably be better to pass along a single object containing all the config, and offer some type information/autocomplete for that:

/**
* @type {GitClerkConfig}
**/
globalThis.gitClerkConfig = {
  ghConfig,
  schemaMap,
  automation,
  customEditorInterfaces,
  generateEnums,
  ...
}
