Subject: [PATCH] feat: Add conditional unpacking support

- Introduced build tags to enable or disable the unpack image functionality
- Added a new file `unpack_image_disabled.go` to handle cases when unpacking is disabled
- Updated existing files to accommodate the new build tag structure

This allows yip consumers to not build the unpack plugin if desired which saves 1243kB of deps from the following deps:

 - github.com/google/go-containerregistry -> 512 kB
 - github.com/docker/docker -> 391 kB
 - go.opentelemetry.io/otel -> 340 kB
