Remove scheme parameter of CreateK8sCR and ORANO2IMSReconciler

[jhernand]

It isn't necessary to explicitly pass the scheme paratemer to the CreateK8sCR function because it can obtain it calling the Scheme() function of the client.

Hmm, I do wonder why kubebuilder adds *runtime.Scheme by default to the Reconciler structure if it's not actually needed 🤔
The controller-runtime example does not use it, so I think we should be ok.

Kindly add more info on this (as a comment here or readme) if you have it, it would be greatly appreciated.

I don't really have more information, just wanted to reduce the number of parameters of the CreateK8sCR function and noticed that the scheme can be obtained from the client. I will take a look at what kubebuilder does and update if I find some better explanation.
