ModuleNotFoundError: No module named 'pip._vendor.chardet'

Expected behavior The command should run successfully and not raise ModuleNotFoundError

Context (Environment)

• OS: Windows 10
• Version of Python: 3.11.9
• Version of pigar: 2.1.4

Additional context

Forcing a downgrade of pip to 20.3 made the error go away. Obviously not a long term solution.

As best I can tell, this error is due to pip dropping its vendoring of the chardet library sometime between versions 20.3 and 24.1.

See here: https://github.com/pypa/pip/tree/main/src/pip/_vendor : chardet is no longer vendored.
