ci: name the dependency check workflow

I think the name hasn't changed in the checks of this PR because the context in which they run is not the same as for pull_requests:

[pull_request_target] runs in the context of the base of the pull request, rather than in the context of the merge commit, as the pull_request event does.

LGTM. (this probably needs updating the branch protection)

Will add the check to required checks, it doesn't seem to be in the list yet.
