`pip debug` causes `AttributeError` in Python 3.13

[eggplants]

Description

When running pip debug in Python 3.13.0a5, it raises AttributeError.

It seems that this error was caused by removal of importlib.resources.open_text in 3.13.

Expected behavior

pip debug doesn't raise AttributeError: module 'importlib.resources' has no attribute 'open_text'

Python version

Python 3.13.0a5

OS

Ubuntu 23.10

How to Reproduce

1. pyenv install 3.13.0a5 && pyenv global 3.13.0a5
