ast.increment_lineno does not increment line numbers in the Module.type_ignores list

Bug report

As indicated in the title, ast.increment_lineno() does not seem to increment the lineno attributes in the Module's list of TypeIgnore objects, with the result that the type ignore list is disconnected from the location attributes in the rest of the AST.

Example:

>>> import sys
>>> print(sys.version)
3.11.0 (main, Oct 24 2022, 19:56:01) [GCC 7.5.0]
>>> import ast
>>> example="""def t():\n  a = 3 # type: ignore"""
>>> tree = ast.parse(example, type_comments=True)
>>> ast.increment_lineno(tree, 10)
<ast.Module object at 0x7fa7505fbe50>
>>> print(tree.body[0].lineno)
11
>>> print(tree.body[0].body[0].lineno)
12
>>> print(tree.type_ignores[0].lineno)
2
