Resolve "Show `failure_reason` and improve failed jobs tab in pipeline detail view"

What does this MR do?

Improves the view of the Failed Jobs tab in the Pipeline detail page.

Are there points in the code the reviewer needs to double check?

By the decision in #44267 (closed) we didn't go with refactoring this into vue or having the Retry button update the page content without refreshing.

Note: still missing a decision/implementation of how to handle smaller screens and what kind of responsiveness we want in the table.

Why was this MR needed?

Consistency.
