filter.fields of EventSource of K8S resource not working as expected

[lauralhm]

Describe the bug
filter.fields of EventSource of K8S resource not working as expected. If I want to monitoring event happened on 2 applications each named as prod-eu-opf-test and prod-eu-opf-test-advance with filter involvedObject.name, then the event happened on application prod-eu-opf-test-advance will been pushed twice: from the event name for prod-eu-opf-test but also for prod-eu-opf-test-advance

**To Reproduce**
Steps to reproduce the behavior:
1. create two applications named as **prod-eu-opf-test** and **prod-eu-opf-test-advance**
2. have following eventsource definition for monitoring the events happened on argocd applications:

apiVersion: argoproj.io/v1alpha1
kind: EventSource
metadata:
  name: eventsource-for-ssp-apps
  namespace: argo-events
spec:
  resource:
    prod-eu-opf-test-updated:
      eventTypes:
        - ADD
      filter:
        afterStart: true
        fields:
          - key: involvedObject.name
            operation: '=='
            value: prod-eu-opf-test
          - key: involvedObject.kind
            operation: '=='
            value: Application
          - key: reason
            operation: '=='
            value: OperationCompleted
          - key: type
            operation: '=='
            value: Normal
      group: ''
      namespace: argocd
      resource: events
      version: v1
    prod-eu-opf-test-advance-updated:
      eventTypes:
        - ADD
      filter:
        afterStart: true
        fields:
          - key: involvedObject.name
            operation: '=='
            value:  prod-eu-opf-test-advance
          - key: involvedObject.kind
            operation: '=='
            value: Application
          - key: reason
            operation: '=='
            value: OperationCompleted
          - key: type
            operation: '=='
            value: Normal
      group: ''
      namespace: argocd
      resource: events
      version: v1

3. trigger the synchronization for app **prod-eu-opf-test-advance**, then watch the eventsource deployment log and found event source will publish two events:

{"level":"info","ts":1721186403.7188642,"logger":"argo-events.eventsource","caller":"eventsources/eventing.go:591","msg":"Succeeded to publish an event","eventSourceName":"eventsource-for-ssp-apps","eventName":"prod-eu-opf-test-updated","eventSourceType":"resource","eventID":"64326563353864362d373436612d346139622d623363362d383739356561383534613565"}
{"level":"info","ts":1721186407.6625366,"logger":"argo-events.eventsource","caller":"eventsources/eventing.go:591","msg":"Succeeded to publish an event","eventSourceName":"eventsource-for-ssp-apps","eventName":"prod-eu-opf-test-advance-updated","eventSourceType":"resource","eventID":"38376361643061632d666230632d346363342d386337642d393434356632333032666532"}


**Expected behavior**
Only the event for app **prod-eu-opf-test-advance** need to be pulished by eventsource. 
Btw, I have checked the source code, I think it's might be this line did the trick: https://github.com/argoproj/argo-events/blob/master/eventsources/sources/resource/start.go#L328

**Environment (please complete the following information):**
 - Kubernetes: v1.27.10
 - Argo: v2.8.5
 - Argo Events: v1.9.2
