Document how to run crane via bazel run

It seems like it should be possible to run rules_oci's crane via bazel run - but I can't figure out the command line

Any guidance would be greatly appreciated!

Start by reproducing the reported question in the rules_oci repository and identify the Bazel target or entry point that exposes crane through bazel run. Verify the command and its arguments, then document the working invocation and expected result; the payload names no specific file or test to update.
