selector with matchFields DoesNotExist does not match

[martyspiewak]

Bug description:

When using the matchFields selector with the DoesNotExist operator, the option does not match when the json path does not exist.

Steps to reproduce:

Please provide a set of steps to reproduce the behavior (example):

1. Apply this supply chain (with some ClusterTemplates first and second):

apiVersion: carto.run/v1alpha1
kind: ClusterSupplyChain
metadata:
  name: test
selector:
  test: true
resources:
  - name: first
     templateRef:
       kind: ClusterTemplate
       options:
         - name: first
            selector:
              matchFields:
                - key: .spec.params[?(@.name=="non-existent")]
                  operator: DoesNotExist
         - name: second
            selector:
              matchFields:
                - key: .spec.params[?(@.name=="non-existent")]
                  operator: Exists

2. Apply this workload:

apiVersion: carto.run/v1alpha1
kind: Workload
metadata:
  name: test
labels:
  test: true
spec:
  params:
    - name: some-param
      value: true

3. Observe status of Workload

Expected behavior:

The first template should match.

Actual behavior:

The status reports an error that 0 templates matched.
