Support `client_secret_post` method in OIDC IdProvider

Description

The upgrade to ScribeJava 5.0 caused the authentication against RPs that do not support `client_secret_basic` to fail (e.g. Office365). We should check in the OIDC configuration whether we can make use of `client_secret_basic` or `client_secret_post` for client authentication purposes.
