[CI] stop_review* jobs failure

Summary

While performing manual environment inspection/cleanup I've noticed long-running environment where stop_review_gke127 (#7430498762) has failed:

Error: uninstall: Release not loaded: rvw-1b777a59: release: not found
$ cleanup
error: You must provide one or more resources by argument or filename.
Example resource specifications include:
   '-f rsrc.yaml'
   '--filename=rsrc.json'
   '<resource> <name>'
   '<resource>'

but due to allow_failure: true in .stop_review_template is being ignored.

As a result we have "ghost" deployment serves no real purpose yet consumes resources and over time prevents proper CI operation when environments become overflown.
