 *  - `editedFilePath` parameter - renamed from the original `ngModulePath` to better reflect it's use
 *  - `metadataField` parameter - allows for more diverse uses such as editing component source files
 *  - `insertedText` parameter - allows for more freedom and flexibility when adding more complicated providers
 *

 * @param metadataField name of the array, where the symbol is added
 * @param symbolName name of the symbol eg. class name
 * @param insertedText the exact text that should be included in the array. If none is provided `symbolName` is used instead
