[Dev][Archery][Crossbow] Comment report bot uses the wrong URL if task run has not started

As discussed on this comment:

https://github.com/apache/arrow/pull/14446#issuecomment-1282067185

Sometimes the task URL that we use on the report is not correct because the job run has not yet started on GitHub forcing us to wait and if not found using the branch URL. On those cases we should use the URL we used to use before ARROW-18028 was merged:

https://issues.apache.org/jira/browse/ARROW-18028

https://github.com/apache/arrow/commit/1e481b5d6dc6537e1994a4ff03334e95c7cfca93

On the case of GitHub:

https://github.com/{repo}/actions?query=branch:{branch}
