Outdated dependency -- Microsoft.Azure.Services.AppAuthentication

[gesownd]

Is there an existing issue for this?

• I have searched the existing open and closed issues

Description

Microsoft.Azure.Services.AppAuthentication v1.6.2 is no longer maintained and should be replaced with Azure.Identity

What is the impact?

Projects using DbUp with MSSQL cannot take advantage of current assemblies due to this dependency.
