Update to the latest c/{common,image} which inclused an update to
docker v28, that update is NOT backwards compatible so I had to fix a
few types.
NOTE: handler.ExecCreateConfig is used directly by the bindings. Thus
this is an API break for pkg/bindings. Including docker types as part of
any stable pkg/bindings API was a very bad idea.
I see no way to avoid that unless we never want to docker v28, which is
not easy as the update comes in from c/image and maybe other packages.
