feat: add custom no_match_error to oci_alias

[thesayyn]

Now when there is no matching platform in oci_alias, users will see an error with list of available platforms from the image.

alias(
    name = "chainguard_static",
    actual = select(
        {
           "@platforms//cpu:x86_64": "@chainguard_static_linux_amd64", 
           "@platforms//cpu:arm64": "@chainguard_static_linux_arm64", 
           "@platforms//cpu:ppc": "@chainguard_static_linux_ppc64le", 
           "@platforms//cpu:s390x": "@chainguard_static_linux_s390x"
         },
        no_match_error = """could not find an image matching the target platform. \navailable platforms are "linux/386", "linux/amd64", "linux/arm/v6", "linux/arm/v7", "linux/arm64", "linux/ppc64le", "linux/s390x" """,
    ),
    visibility = ["//visibility:public"],
)

fixes #178
