Description
What happened?
We have composition that generates or consumes values with a high level of nested sub-values. (Those are CRDs that we are using with the Kubernetes Provider)
When going over 30 levels of imbrication the error below is raised
crossplane: error: cannot render composite resource: cannot run pipeline step "blueprint": rpc error: code = Unknown desc = Unexpected <class 'google.protobuf.message.DecodeError'>: Error parsing message with type 'apiextensions.fn.proto.v1.RunFunctionRequest'
How can we reproduce it?

Running ☝ this composite would faild if there is a level30 as child of level29.
Could this be linked to the limits set in Protobuf (protocolbuffers/protobuf#6537) ?
Note: there is no issue when outputing resources with more than 30 levels. (ie: running something like
rsp.desired.resources["toto"].resource.update(resources)
Where resources has more than 30 levels.
It is only when the function is called with too many depth inputs that the exception is raised.
