Lists Azure.Identity >= 1.11.4 but only >= 1.14.2 is not deprecated
Reason is "This version takes a dependency on a deprecated version of MSAL .NET (Microsoft.Identity.Client)."
And the version used in main is >=1.13.2 i.e also deprecated (unexpected that Directory.Packages.props is not used for version handling took some searching to find where the version was coming from.)

And 6.1.0 lists 1.13.2 which is also deprecated.

Maybe there are some other dependencies that could get an update as well?
