[Bug] When using dSTS authority with WithTenantId & have applied fix from: #4144, get cast error

[jennyf19]

Unable to cast object of type 'Microsoft.Identity.Client.Instance.DstsAuthority' to type 'Microsoft.Identity.Client.Instance.AadAuthority'.

On this line: https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/blob/main/src/client/Microsoft.Identity.Client/ApiConfig/AbstractAcquireTokenParameterBuilder.cs#L277

If a dSTS authority is used, the code is casting for an AadAuthority, but AuthorityInfo is dSTS, so the cast fails:

AadAuthority aadAuthority = (AadAuthority)ServiceBundle.Config.Authority;

You have a test checking for dSTS authority types here, but it's using [WithTenantIdFromAuthority](

microsoft-authentication-library-for-dotnet/src/client/Microsoft.Identity.Client/ApiConfig/AbstractAcquireTokenParameterBuilder.cs

Line 301 in 18fc352

public T WithTenantIdFromAuthority(Uri authorityUri)

which is not what we use in Id Web, we use .WithTenantId().
