Subject: [PATCH] PlatformCredentialsSet: configure
 spec.preserveUnknownFields=false

Explicitly set `preserveUnknownFields: false` to enable strict
CRD validation and prohibit unknown fields in test environment first.

Conversion of CRD from v1beta1 to v1 (see #2991) resulted in
`preserveUnknownFields: true`:
```
$ kubectl --context=example get crd platformcredentialssets.zalando.org -o yaml | grep preserveUnknownFields
  preserveUnknownFields: true
    message: 'spec.preserveUnknownFields: Invalid value: true: must be false'
```
and requires explicit false value to reset.
