drop git-init from the list of published images

The recent release creation failed with:

Expected images did not match: Images ['gcr.io/tekton-releases/github.com/tektoncd/pipeline/cmd/git-init:v0.46.0'] were expected but missing.

We no longer create git-init image in a seperate commit -
81876e6

Updating the image publish task to not publish git-init image.
