Allow scope to be passed as array (#150)

* feat: Allow scope to be passed as array

Scopes are currently passed as a scope string, separating scopes by
spaces.
Clients can grow to many scopes, resulting in a very long string.

This change allows us to specify scopes using the property scopeArray.
That way, we can separate scopes by newlines.
Additionally, this allows us to comment a single scope temporarily or
add a comment for a specific scope, e.g. as a reason why that client has
this scope granted.

* feat: Deprecate scope in favor of scopeArray

* feat: Use kubebuilder:deprecatedversion
