AzureDeveloperCliCredential.get_token timed out with Python 3.12 on Ubuntu

[hanohrs]

I know that this project only supports Python 3.9, 3.10, or 3.11, but I think it's worth sharing.

When I run scripts/prepdocs.sh with Python 3.12, I get the following error. (USE_LOCAL_PDF_PARSER="true")

After I built Python 3.11 from the source and modify scripts/load_python_env.sh to use Python 3.11, it works fine.

Modifying .venv/lib/python3.12/site-packages/azure/identity/aio/_credentials/azd_cli.py to return _SyncAzureDeveloperCliCredential from get_token also fixes this issue.
