In `Namespace#find_by_pages_host` we always have top level namespaces
which means we can use `find_by_path` instead of `find_by_full_path` and
avoid join on `routes`.

Remove 422 response body logging

We can do this now that we have merged CE/EE, the variable
is no longer needed.

The following merge requests fixed a bug we had in the docs
pipeline, but introduced another:

- https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/731
- https://gitlab.com/gitlab-org/gitlab-docs/-/merge_requests/734

Namely, forks cannot use the project-set $DOCS_GITLAB_REPO_SUFFIX
variable, so they will fail at the internal links test. For example
https://gitlab.com/briankabiro/gitlab-ee/-/jobs/460294523.

Nanoc would create the content under 'public/doc/', whereas it should
be 'public/ee/', since we have some hardcoded links set in
https://gitlab.com/gitlab-org/gitlab-docs/-/blob/887850752fc0e72856da6632db132f005ba77f16/content/index.erb#L44-63

When routing paths to exposed job artifacts, we were always using the
destination project. However, in a cross-project MR, the job exposing
the artifacts is run in the source project, not in the destination
project. Change the arguments to project_job_path() to always use the
job's project for constructing the URL path.

!23738 tried a more expansive fix but this wasn't doable thanks to
project_job_path() also being a hidden Rails-generated helper function
which did take both project and job as an argument.

This provides better nesting for tracing.

It should be NotesFinder as that's the class we are testing. This
escaped detection by the FilePath cop because it was a string

Also, used described_class in the spec now.
