E2E Tutorial: Use dynamic port & url for func yaml

[Leo6Leo]

The registry route should be updated to dynamic, and use the one that's being provided by the user input.
Also the @sha hash in those func.yaml file seems like causing some errors in the func deploy process. I didn't manage to use func deploy to deploy those ML services. Will continue tmr or the day after.

Want do make those changes in a follow up?
