fix: Security Factory failed when multiple specs is used in same configuration

[42atomys]

Describe the bug
When multiple specs is provided, all security pipelines of previous definition is overrided by the last.

To Reproduce
Steps to reproduce the behavior:

1. My config is

apiVersion: v1alpha1
observability:
  metricsEnabled: true
specs:
- name: exampleHook
  entrypointUrl: /webhooks/example
  security:
  - header:
      inputs:
      - name: headerName
        value: X-Hook-Secret
  - compare:
      inputs:
      - name: first
        value: '{{ .Outputs.header.value }}'
      - name: second
        valueFrom:
          envRef: HOOK_SECRET
  storage:
  - type: redis
    specs:
      host: localhost
      port: '6379'
      database: 0
      key: foo
- name: gitlab
  entrypointUrl: /webhooks/gitlab
  security:
  - header:
      inputs:
      - name: headerName
        value: X-Gitlab-Token
  - compare:
      inputs:
      - name: first
        value: '{{ .Outputs.header.value }}'
      - name: second
        valueFrom:
          envRef: GITLAB_WEBHOOK_TOKEN
  storage:
  - type: redis
    specs:
      host: localhost
      port: '6379'
      database: 0
      key: gitlab

2. Try to store following payload

env DEBUG=true GITLAB_WEBHOOK_TOKEN=houk2 curl --request POST \
  --url http://localhost:8080/v1alpha1/webhooks/example \
  --header 'Content-Type: application/json' \
  --header 'X-Gitlab-Token: houk2' \
  --data '{
	"type": 42,
	"payload": {
		"nested": "amazing"
	}
}'

3. See error

Expected behavior
The security line need to return 401 due to missing X-Hook-Secret header in her spec definition.
