Incorrect information about exception raised if source contains null bytes for ast.parse() and compile() #122461

Description

@devdanzin

Documentation

Docs for compile() and ast.parse() say they raise ValueError for source contains null bytes. However, since 3.12 (#97594), SyntaxError is raised instead:

>>> compile("\x00", "lambda.tt", "exec")
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    compile("\x00", "lambda.tt", "exec")
    ~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
SyntaxError: source code string cannot contain null bytes

This function raises :exc:`SyntaxError` if the compiled source is invalid,
and :exc:`ValueError` if the source contains null bytes.

And
If source contains a null character (``\0``), :exc:`ValueError` is raised.
