parse.y: Fix the last location of NODE_STR in %w

  * parse.y: Use @2 to only include a range of tSTRING_CONTENT.

  e.g. The locations of NODE_STR is fixed:

  ```
  %w[a]
  ```

  * Before

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 5)
  ```

  * After

  ```
  NODE_STR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 4)
  ```
