fix(adyen): Handle Adyen::AuthenticationError when creating the custo…

…mer (#2820)

## Description

This Pull Request adds the handling of `Adyen::AuthenticationError` in
the `PaymentProviderCustomers::AdyenService#create` method.
It will keep delivering an error webhook, but will not raise the
authentication error anymore as nothing can be handled at Lago's level.

NOTE: In a future, the related `PaymentProvider` should marked as
failed/disconnected/invalid and the error logged to make it visible in
the web application and in the API
