mypy on python3.12 raises `DeprecationWarning` from `ast`

[jakkdl]

Bug Report

From https://docs.python.org/3.12/whatsnew/3.12.html

• The following ast features have been deprecated in documentation since Python 3.8, now cause a DeprecationWarning to be emitted at runtime when they are accessed or used, and will be removed in Python 3.14:
  * ast.Num
  * ast.Str
  * ast.Bytes
  * ast.NameConstant
  * ast.Ellipsis

Use ast.Constant instead. (Contributed by Serhiy Storchaka in gh-90953.)

Raised in fastparse.py, but haven't checked if they're present elsewhere

mypy/mypy/fastparse.py

Lines 133 to 151 in 3d2f437

	# TODO: Num, Str, Bytes, NameConstant, Ellipsis are deprecated in 3.8.
	# TODO: Index, ExtSlice are deprecated in 3.9.
	from ast import (
	AST,
	Attribute,
	Bytes,
	Call,
	Ellipsis as ast3_Ellipsis,
	Expression as ast3_Expression,
	FunctionType,
	Index,
	Name,
	NameConstant,
	Num,
	Starred,
	Str,
	UnaryOp,
	USub,
	)
