crane: fails on Windows with "Error: cannot parse hash: "sha256\\0401ae60059d7270e280bdd6db0d3b91afcf5b34be7271d39c2af0253479257b""

Describe the bug

We use rules_oci Bazel rules to build an OCI image. oci_image delegates to crane by invoking the following commands:

++ external/oci_crane_windows_amd64/crane.exe registry serve --disk=bazel-out/x64_windows-fastbuild/bin/my-project/app-oci-image/blobs --address=localhost:0

++ external/oci_crane_windows_amd64/crane.exe push bazel-out/x64_windows-fastbuild/bin/external/zulu_openjdk_17_single/layout 127.0.0.1:5126/layout:latest
