Frontend: Remove collapsible section in failed MR widget
Summary
At the moment, the failed MR widget contains a collapsible section that contains a dump of log information related to the reason for the error. Since larger failed errors in a pipeline mean more logs to pull and it has determined that it doesn't add a lot of value now with the RCA feature being available, this issue is to remove the collapsible section so that the failed MR widget can be release globally beyond just gitlab-org (which is the only project that can see it now under the feature flag).
In the future (outside of scope for this issue), we may incorporate a button/link to initiate the RCA feature for the failed job.
Proposal
Remove collapsible section of failed MR widget and release feature globally.
Confirm purpose and User Reception (how does this benefit the user?)
Less scrolling for a user when there are a lot of failed jobs but they can still access the failed job in the link that exists already in the widget.
