Internal typo in `RuleCollectorVisitor.rulses` attribute

Bug report

Bug description:

The RuleCollectorVisitor visitor class in Tools/peg_generator/pegen/parser_generator.py has a typo in its attribute, making it annoying for subclasses should they access this attribute. Since the file is internal, there shouldn't be any breakage but I will still create an issue for tracking it just in case.
