Make it easier to traverse errors in job log

Problem

Currently, with a long job log, it's difficult to traverse and identify individual errors. Most of the log doesn't contain errors, so sometimes it's difficult to find the errors quickly.

Proposal

We currently have a way to scroll to the bottom or top of the log, however, I just use my mouse wheel to do this anyways. We should have a method for traversing through all the errors, similar to how you can "jump" to different unresolved threads in issues/MRs.

Bonus

It might also be useful to include a button to Copy file location instead of having to highlight, copy and paste the file location to then search for the file locally in your IDE.
