bug: wrong `reference types` in community plugins

[robingenz]

The generated value in reference types always has the prefix @capacitor. However, community plugins have a different scope or no scope at all.

Example (see https://github.com/robingenz/capacitor-firebase/blob/main/packages/authentication/README.md#examples):

/// <reference types="@capacitor/firebase-authentication" />

import { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  plugins: {
    FirebaseAuthentication: {
      skipNativeAuth: false,
      providers: ["apple.com", "google.com"],
    },
  },
};

export default config;

/// <reference types="@capacitor/firebase-authentication" /> should be /// <reference types="@capacitor-firebase/authentication" />.
