Display a link to all other errors in the scenario

# Display a link to all other errors in the scenario

## Context

When a scenario has several errors we can view the detail of one error, then close the detail, go to the next...
It can be good to be able to go to the error details of all the other errors of the scenario, to give the current one a context.

## Expected

Here is a quick and dirty mockup of how it could look like:
Or each red step could simply be a clickable link
(still a black text, but with underlining to make it clear it's clickable).

No files, tests, or entry points are named. Start by locating the scenario error-detail view and the rendering of its error steps, then compare the existing UI with the linked mockup. Done means users can navigate from one error to the other errors in the same scenario.
