• Package Name: azure-identity
• Package Version: 1.23
• Operating System: Windows
• Python Version: 3.12.0 - 3.12.7

Describe the bug
The error occurs when using AzureCliCredential with Python version 3.12.0 - 3.12.7.

The AzureCliCredential get_token_base uses shutil.which to locate the Az Cli-executable. For the named Python-versions, shutil.which returns the path to the az-executable used by e.g. PowerShell, although Python needs the path to the az.CMD-executable.

A part of shutils.which for Python version 3.12.0 on Windows is implemented using this: files = [cmd] + [cmd + ext for ext in pathext] where [cmd] is equivalent to [az].

The first part returns the the path to az-executable, which returns "Failed to execute 'c:\Program Files\Microsoft SDKs\Azure\CLI2\wbin\az'" for subsequent subprocess-calls. This is later removed by patched versions of Python 3.12.

To Reproduce
Steps to reproduce the behavior:

1. Install Python 3.12.0
2. Run AzureCliCredential with get_token("./default")
