crane: GCR images are not up to date

### Describe the bug

Crane docker images that are intended to be available at `gcr.io/go-containerregistry/crane[version]` and `gcr.io/go-containerregistry/crane/debug:[version]` are not currently up to date.

It would appear the most recent docker container release for the GCR registry is August 2023

The docker images are documented as being available via the GCR registry over at https://github.com/google/go-containerregistry/blob/8dadbe76ff8c20d0e509406f04b7eade43baa6c1/cmd/crane/README.md#images

### To Reproduce

1. Run the command `docker run -it gcr.io/go-containerregistry/crane/debug:v0.19.0`
2. Observe the image not being pulled, as it does not exist

Or

1. Navigate to gcr.io/go-containerregistry/crane/debug
2. Sort the images by created date
3. Observe the most recent image as occurring on 1st August, 2023

### Expected behavior

Crane Images should be published to the GCR registries for each release

Start with the documented image locations in cmd/crane/README.md and reproduce the missing image with docker using gcr.io/go-containerregistry/crane/debug:v0.19.0. Trace the release process that should publish the crane and crane/debug images, then verify that images are available in GCR for each release.
