Types for `@analytics/google-tag-manager`

[borasemiz]

Hello,

The analytics package has built-in TypeScript types. It would be great if its plugin packages, like @analytics/google-tag-manager, have type declarations as well.

I'm currently using this fallback:

declare module '@analytics/google-tag-manager' {
  import type { AnalyticsPlugin } from 'analytics';

  export interface GoogleTagManagerConfig {
    auth?: string;
    containerId: string;
    customScriptSrc?: string;
    dataLayerName?: string;
    debug?: boolean;
    execution?: string;
    preview?: string;
  }

  function googleTagManager(config: GoogleTagManagerConfig): AnalyticsPlugin;

  export default googleTagManager;
}

It might not be perfect, but it does help us for now.
