Description

TokenAcquisition ServiceCollectionExtensions is checking for ICredentialsLoader against ImplementationType. It either needs to check ICredentialsLoader against ServiceType or ImplemenationType against DefaultCredentialLoader

See:

https://github.com/AzureAD/microsoft-identity-web/blob/master/src/Microsoft.Identity.Web.TokenAcquisition/ServiceCollectionExtensions.cs#L48

Reproduction steps

1. Register a custom ICredentialsLoader
2. Try to use an API that uses the credentials loader
