CUS-534 Document platform error for image pull failure in custom deployment

indd it is the platform which is incorrect, I'll atleast add it in the docs here https://console.settlemint.com/documentation/docs/using-platform/custom-deployment/#limitations-and-considerations:

[custom-deployment][ErrImagePull] rpc error: code = NotFound desc = failed to pull and unpack image "http://ghcr.io/settlemintindia/bond-fractionalization-app:latest|ghcr.io/settlemintindia/bond-fractionalization-app:latest": no match for platform in manifest: not found
