Allow incomplete CustomResources in crossplane.Request

[Avarei]

What problem are you facing?

This function could be used in situations where it is only responsible for a subset of all resources.
Currently crossplane.Request throws an exception if a CustomResource is in RunFunctionRequest, which is not in the map of CustomResources.

function-pkl/pkl/crossplane.contrib.example/compositions/steps/full.pkl

Lines 9 to 18 in c8b4f77

	local request = new crossplane {
	customResourceTemplates = new {
	["XR"] {
	["example.crossplane.io/v1"] = XR
	}
	["Object"] {
	["kubernetes.crossplane.io/v1alpha2"] = Object
	}
	}
	}.Request

How could this Function help solve your problem?

If a resource is not defined crossplane.pkl should gracefully return a resource similar to unstructured.Unstructured.
