Update docker/distribution to 2.8.0

[ph]

Advisory:

Due to an oversight in the OCI Image Specification that removed the embedded mediaType field from
manifests, a maliciously crafted OCI Container Image can cause registry clients to parse
the same image in two different ways without modifying the image’s digest by modifying the
Content-Type header returned by a registry. This can invalidate a common pattern of relying
on container image digests for equivalence.

Looking at the e2e test this look like a failure in ansible bootstrap and created elastic/e2e-testing#2164
