Empty Label Selector does not get propegated to crossplane

[Avarei]

What happened?

when setting an empty labelSelector

extraResources:
  - kind: EnvironmentConfig
    into: envConfs
    apiVersion: apiextensions.crossplane.io/v1alpha1
    type: Selector
    selector:
      maxMatch: 2
      minMatch: 1
      matchLabels: []

does not propagete an empty labelSelector to crossplane. instead omitting it altogether.

empty LabelSelectors imply they should match everything.
from api docs:

A selector to restrict the list of returned objects by their labels. Defaults to everything.

How can we reproduce it?

replace

matchLabels:
  - key: type
    type: Value
    value: cluster

with

matchLabels: []

in example/composition.yaml

What environment did it happen in?

Function version: v0.0.3
Crossplane 1.16.0
