update sig-storage image list and promotion script

The COSI project has 2 images that need to be promoted to the k8s.io
registry for its latest release.

COSI staged images previously had multiple tags including the semver
tag. The sig-storage `generate.sh` script doesn't output multi-tagged
images correctly, so COSI modified its release tagging to use only the
semver tag for staged release images. In order to filter out existing
staged COSI images that have multiple tags, introduce an inverted grep
to the script in this commit.

Run the script to generate an updated `images.yaml`.
