Bug: Change the way how we are matching provider name with managed resource

[Hubert-Szczepanski-SAP]

Understand the Task

At the moment we are matching provider name, by looking into managed resource metadata.spec.providerConfigRef and getting name from it.
There are two issues that can happed:

1. There is no providerConfigRef
2. Name from provider config would = default (we can end up with few different 'default' names for different providers)

Solution - get provider from apiVersion.

apiVersion: account.btp.sap.crossplane.io/v1alpha1

We then have a mapping list in the frontend:

{
  "btp-provider": [
    "btp.sap.crossplane.io"
  ],
  ...
}

Any further valuable resources.
