Implement pre-build repository check for Replicate images (#1733)
* Implement pre-build repository check for Replicate images
- Added `ManifestInspect` function in `pkg/docker` to use `docker manifest inspect` for verifying if an image exists on a registry.
- Updated `push` function in `pkg/cli/push.go` to call `ManifestInspect` before building, specifically for Replicate images.
- Ensured early feedback if the model does not exist on Replicate, preventing unnecessary build time and resources.
