[3.14] gh-133555: Allow regenerating the parser with Python < 3.14 (GH-133557) (#133630)

# When adding new tokens, remember to update the PEG generator in
# Tools/peg_generator/pegen/parser_generator.py
# This will ensure that older versions of Python can generate a Python parser
# using "python -m pegen python <GRAMMAR FILE>".
