Create graphQL field for Traces of Failed Jobs

What does this MR do and why?

We'll need a way to return failed traces for builds in graphQL. This is so the FE can migrate away from REST and into graphQL to request failed job traces. This is defaulted to last 10 lines, as that is the standard currently for the UI.

Existing REST method the FE uses currently: https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/helpers/ci/builds_helper.rb#L10

Did not want to make this customizable, as it'll increase the potential to overwork the system. Some traces have thousands of lines so we want to hard cap it.
