Negative integers are not parsed

Issue is _number being used as choice in literal, but also as part of _decimal_number.

    literal: $ => prec(2,
      choice(
        $._number,
        $._decimal_number,
        $._literal_string,
        $.keyword_true,
        $.keyword_false,
        $.keyword_null,
      ),
    ),
    _double_quote_string: _ => seq('"', /[^"]*/, '"'),
    _literal_string: $ => choice(
      seq("'", /[^']*/, "'"),
      $._double_quote_string,
    ),
    _number: _ => /\d+/,
    _decimal_number: $ => choice(
        seq(optional("-"), ".", $._number),
        seq(optional("-"), $._number, ".", $._number),
        seq(optional("-"), $._number, "."),
    ),

Therefore, \d+ is correct, and a new anonymous option _integral_number must be added, using seq(optional("-"), $._number).
