[release-v1.18] Add dockerfile generator (#668)

Running `make generate-release` fails, as the generate.sh file does not
exist (e.g. in the current
[generate-ci](https://github.com/openshift-knative/hack/actions/runs/14658039185/job/41136450034)
runs).
This PR adds it. 

:exclamation: It still references the func-util and event-plugin images
from the `serverless-operator-136` repo, as they don't have builds for
1.38 yet. This needs to be adjusted, as soon we have the 1.38 builds
available
