fix: correct goreleaser release image name
What
This MR corrects the docker image name.
Why
v3.50.1 was published to https://gitlab.com/gitlab-com/gl-infra/platform/runway/runwayctl/container_registry/8068974 as gitlab-com/gl-infra/platform/runway/runwayctl instead of gitlab-com/gl-infra/platform/runway/runwayctl/runwayctl.
