PipeCD gets diff with bool value in Cloud Run manifets

[Tetsuya Yamamoto]

What happened: With Cloud Run application, when we set a bool value for env, PipeCD gets diff the env, like following.
Manifest is

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  name: xxx
spec:
  template:
    spec:
      containers:
        - name: xxx
          env:
            - name: XXX
              value: false

PipeCD console is

      spec:
        containers:
          - env:
              -
                #spec.template.spec.containers.0.env.10.value
-               value: false
+               value: <bool Value>
