Delay docker image updates in GitLab Agent
This change set delays updates to the docker image referenced in the GitLab pipeline of the GitLab Agent project by 1 day.
The reason for this is that for some unknown reason it takes almost a day for docker to release all their image variants - especially the linux/arm64 takes a while.
An example of this behavior can be observed here: gitlab-org/cluster-integration/gitlab-agent!1632 (merged)
