github workflows: modify Gitlab CI trigger

In 5e639cba6f the context of the Trigger
Gitalb CI workflow changed and the context
"github.event.pull_request.draft" is no longer available so the
condition for SKIP_CI didn't work. This can be fixed by getting the
variable in the previous workflow and passin it as artifact. Docs:
