az loginDescription
Bump MSAL from 1.36.0 to 1.39.0 in Azure CLI core and the platform-specific requirements files.
MSAL 1.39.0 includes AzureAD/microsoft-authentication-library-for-python#926, which disables broker authentication on Intel Macs and x86_64 Python running under Rosetta, allowing authentication to fall back to the non-broker flow.
