A pin outside semver was given its own 'docker-ref' marker on the theory
that every class needs one. That holds for a digest and not for a tag. A
digest pin declares something about the registry, that bytes move under a
standing tag, which no other choice says. A tag outside semver declares
that upstream publishes nothing orderable, which is exactly what
'docker-version' already means and what minio and the act runner already
carry on their version lines.
Keeping both would have put '# nocheck: docker-version, docker-ref' on
every such line: two keys, two checks, one sentence said twice. 'docker-ref'
is dropped instead. It lived in this one mapping, was never entered in the
suppression catalog, and no check ever read it.
The semver entry goes with it, because a semver pin never needs a
declaration. The test that asserted three distinct rules is replaced by two
that pin the separation where it is real: a digest marker differs from a
tag marker, and a semver pin has no marker at all.

A digest pin was emitted as `name:sha256:...`, which no registry accepts:
image_source('ghcr.io/.../csp-checker', 'sha256:d559...') returned
'ghcr.io/.../csp-checker:3.0.0'. The separator depends on the pin class, so
the class has to be decided before the reference is built.
utils/docker/image/pin.py names the three classes in preference order
(semver, then digest, then a general ref that no registry can order) and
maps each to the nocheck marker that declares it. Both discovery entry
points now end in pull_reference(), so '@' versus ':' is decided in one
place instead of at every call site.
The semver pin lint points a digest at 'docker-digest' instead of
'docker-version', so the two fallbacks stay distinguishable in the
suppression catalog. It stays warn-only.
