Add submodule to contain test source and destination

I've created a submodule called ai_migration_example. On installation it creates a content type called Easy Migration Example with fields that match what we're already pulling in our AiMigrator service:

   $bundle = (object) [
      'title' => '',
      'introduction' => '',
      'resource URL' => [
        'text' => '',
        'url' => '',
      ],
      'authors' => [],
      'abstract' => '',
      'related topics' => [
        [
          'text' => '',
          'url' => '',
        ],
      ],
    ];

Adding a sample migration yml file and a custom data parser plugin will be in a future issue.

Taking a look.

Content-type looks good. Thank you majorrobot
