[Bug] When using .WithTenantId() with a dSTS authority, get tenant_override_non_aad error

[jennyf19]

Based on testing from @JoshLozensky with Id Web and a dSTS authority, we are getting:

        ErrorCode: tenant_override_non_aad
Microsoft.Identity.Client.MsalClientException: WithTenantId can only be used when an AAD authority is specified at the application level.
   at Microsoft.Identity.Client.AbstractAcquireTokenParameterBuilder`1.WithTenantId(String tenantId)

Because MSAL is not including dSTS in the tenant override, only AadAuthority:

internal bool IsTenantOverrideSupported => AuthorityType == AuthorityType.Aad;
