Superfluous 'output' workspace defined in git-cli env

[the-it-jaeger]

https://github.com/tektoncd/catalog/blob/96c4ea272d13efceabc26626fe80f83e017b43d9/task/git-cli/0.4/git-cli.yaml#L105-L106

I see no reference to this workspace anywhere else, and it's causing my PipelineRun to fail with:

expected workspace "output" to be provided by pipelinerun for pipeline task "update-image-tag"

Where the update-image-tag Task has taskRef: git-cli

I did not get the error with OpenShift Pipelines 1.14, but I do with OpenShift Pipelines 1.15. Upstream Tekton version translations below.

Adding a little 'output' workspace binding gets around this problem.

    - name: output
      volumeClaimTemplate:
        spec:
          accessModes:
            - ReadWriteOnce
          resources:
            requests:
              storage: 1Mi

Emptydir probably works just as well.
