Can't use azure dns provider with non-azure infrastructure provider

[j2L4e]

/area control-plane /kind regression /platform azure

What happened: We run shoots on hetzner cloud. Since hetzner doesn't support managing dns, we use the azure-extension to handle dnsrecords for hcloud shoots. Since #815 the dnsrecord reconciler throws errors because it can't decode a non-azure cloudprofile's providerConfig:

could not decode providerConfig of cloudProfile for 'hcloud': no kind "CloudProfileConfig" is registered for version "hcloud.provider.extensions.gardener.cloud/v1alpha1" in scheme

What you expected to happen: The extension should reconcile dnsrecords.

How to reproduce it (as minimally and precisely as possible):

• Create a non-azure shoot.
• Add an azure-dns dns provider
• Create a dns-record for that provider

Anything else we need to know?:

Environment:

• Gardener version (if relevant): 1.94
• Extension version: 1.43.1
• Kubernetes version (use kubectl version): 1.28.9
• Cloud provider or hardware configuration: azure/hcloud
