Change Jira service to create comments first

What does this MR do?

Issue #195794 (closed)

• As discussed with @nhxnguyen, I wanted to try a speculative fix to the Jira issue to try and create a comment before creating the remote link. This is closer to what the code was doing in %12.5.
• I have also reverted some code to be closer to the original here: https://gitlab.com/gitlab-org/gitlab/-/blob/c77bb71ca5944cdaa6d045ee821c29d809ef2624/app/models/project_services/jira_service.rb#L274. This was from this discussion !26052 (comment 295886903) to fix an old bug.
• As discussed here #198411 (comment 295077110), changed the logging key name to try to avoid the response getting filtered.
