upgrade gitlab-runner to alpine-v17.0.1
In the most recent GitLab upgrade all runners were updated to 17.0.1. The new patch version contains just one bug fix which we don't need(?), see https://gitlab.com/gitlab-org/gitlab-runner/blob/v17.0.1/CHANGELOG.md#v1701-2024-07-05
So feel free to decide to merge or close this MR.
