fix: correct ref and ref_name (#1672)

* fix: correct ref and ref_name

The ref in the GitHub context is always full qualified
(e.g. refs/heads/branch, refs/tags/v1).
The ref_name is the ref with the strippep prefix.
In case of pull_requests, this is the merge commit ref
(e.g. refs/pull/123/merge -> 123/merge).

* test: update test data
