replace reference/docker for github.com/distribution/reference v0.5.0

The reference/docker package was a fork of github.com/distribution/distribution,
which could not easily be used as a direct dependency, as it brought many other
dependencies with it.

The "reference' package has now moved to a separate repository, which means
we can replace the local fork, and use the upstream implementation again.

The new module was extracted from the distribution repository at commit:
b9b19409cf
