Function failed to build after renaming the used secret

[lizzzcai]

Description
Function failed to build after renaming or deleting the secret used previously

Environmental
Tell us what your cluster environment is like, e.g.

• Operating System Information
• kubernetes version: 1.21.5
• OpenFunction version: latest
• Versions of dependent components (e.g. dapr, keda, shipwright, knative)
  • Shipwright: v0.6.0

Expected behavior
The Function should be able to build even the push secret being deleted

Actual behavior
Once I delete the push-secret and create another secret with a different name (push-secret-new), ofn is not able to build the function

To Reproduce

1. create a push secret: push-secret
2. build a function

apiVersion: core.openfunction.io/v1alpha2
kind: Function
metadata:
  name: function-sample
spec:
  version: "v1.0.0"
  image: "openfunctiondev/sample-go-func:latest"
  imageCredentials:
    name: push-secret
  port: 8080 # default to 8080
  build:
    builder: openfunction/builder:v1
    env:
      FUNC_NAME: "HelloWorld"
      FUNC_TYPE: "http"
    srcRepo:
      url: "https://github.com/OpenFunction/samples.git"
      sourceSubPath: "functions/Knative/hello-world-go"
  serving:
    runtime: "Knative" # default to Knative
    template:
      containers:
        - name: function
          imagePullPolicy: Always

3. delete the push-secret and create a new one called: push-secret-new
4. build the function again

apiVersion: core.openfunction.io/v1alpha2
kind: Function
metadata:
  name: function-sample-new
spec:
  version: "v1.0.0"
  image: "openfunctiondev/sample-go-func:latest"
  imageCredentials:
    name: push-secret-new # <-update the secret
  port: 8080 # default to 8080
  build:
    builder: openfunction/builder:v1
    env:
      FUNC_NAME: "HelloWorld"
      FUNC_TYPE: "http"
    srcRepo:
      url: "https://github.com/OpenFunction/samples.git"
      sourceSubPath: "functions/Knative/hello-world-go"
  serving:
    runtime: "Knative" # default to Knative
    template:
      containers:
        - name: function
          imagePullPolicy: Always
