parse.y: fix up r56198

Browse source 
* parse.y (symbol, dsym, parser_set_number_literal): set state to
  ENDARG, so that `do` after a literal should be `do_block` and
  bound to the outer method.  [ruby-core:72482] [Bug #11873]
* parse.y (parse_ident): revert r56198.
* parse.y (warn_balanced): the state of symbol and numeric
  literals is now EXPR_ENDARG, do not exclude it.
