This updates github.com/opencontainers/image-spec/schema subpackage from an obsolete .../jsonschema/v5 to /v6 . We use these dependencies only in tests, so it doesn't matter that much, but removing references to years-old unmaintained versions makes it easier to check / remove other such cases. (This is test-only, so the added files in vendor/ do not mean a larger binary size; it's almost exactly unchanged.) Signed-off-by: Miloslav Trmač <mitr@redhat.com>
