parse.y: Fix locations of dsym

* parse.y: Fix to only include a range from tSTRING_BEG to tLABEL_END.

  e.g. The locations of the NODE_LIT is fixed:

  ```
  { "a": 10 }
  ```

  * Before

  ```
  NODE_LIT (line: 1, code_range: (1,2)-(1,9))
  ```

  * After

  ```
  NODE_LIT (line: 1, code_range: (1,2)-(1,6))
  ```
