Reexport existing typings, CKEditorModule, and CKEditorComponent from the main file.

[ma2ciek]

For now, to use typings somebody would need to type import { CKEditor5 } from '@ckeditor/ckeditor5-angular/ckeditor. Similarly using the CKEditorComponent.

Both files can be re-exported from the main package though:

// ckeditor.module.ts
@NgModule( {
	// ...
} )
export class CKEditorModule {}

export * from './ckeditor';
export { CKEditorComponent } from './ckeditor.component';
