ast.parse() abuses assert for error checking

[jwilk]

Bug report

ast.parse() uses the assert statement to validate the feature_version argument:

$ python3 -c 'import ast; ast.parse("print", feature_version=(2, 7))'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/jwilk/.local/lib/python3.11/ast.py", line 45, in parse
    assert major == 3
AssertionError

This is bad because the check will go away if you enable optimizations:

$ python3 -O -c 'import ast; ast.parse("print", feature_version=(2, 7))' && echo yay
yay
