We need to increase the timeout of the after_script, as otherwise not
all artifacts might be uploaded on larger runs like "-t fast". We need
to add [1]

variables:
  RUNNER_AFTER_SCRIPT_TIMEOUT: 15m

I'll add it in case a v2 is needed. Otherwise it can also be added
later one, when more evidence around resonable timeouts are gathered.
