jsdoc/require-returns-check: False positive for overloads

[iliubinskii]

Sample:

  /**
   * Description.
   *
   * @returns Result.
   */
  function f(): string;

  function f(): string {
    return "Result";
  }

Expected behavior

No warnings.

Actual behavior

Getting warning:
JSDoc @returns declaration present but return expression not available in function

If this plugin is not using typescript then at least it might ignore overloads with additional option.

This looks like it may be a dupe of #903 .

Closing as a dupe though feel free to comment further as necessary.
