Please provide `debug` images tagged with specific versions

Currently, the `*rane` Docker images are available from gcr.io with two kinds of tags for slightly different images:

1. Minimal images tagged with specific versions, e.g. `v0.20.3`.
2. Images with included `sh` binaries, tagged just `debug`.

(1) is obviously what you want to ensure some degree of reproducibility, but (2) tends to be much more convenient to use in CI. Even the [`crane` README itself uses the `debug`-tagged image for the GitLab CI example](https://github.com/google/go-containerregistry/blob/59a4b85930392a30c39462519adc8a2026d47181/cmd/crane/README.md#using-with-gitlab).

Would it be possible to provide debug images like (2) but tagged with specific versions, e.g. `v0.20.3-debug`? That would offer the best of both worlds.
