With the new job-based file copy, fetching results takes longer. We thus have to increase the long running update test check times in order not to run into bogus release test failures.
Also fixes artifact uploading issues.
This fixes the previous problems from team column revert.
This has 2 additional changes;
alert handler receives the team argument, which was the root cause of breakage; https://github.com/ray-project/ray/pull/21289
Previously, tests without a team column were raising an exception, but I made the condition weaker (warning logs). I will eventually change it to raise an exception, but for smoother transition, we will log warning instead for a short time
