Add a redirect status as a success

What does this MR do and why?

Job authentication logs are not being populated when job artifacts being requested using CI_JOB_TOKEN

This MR fixes a bug Job authentication logs not populating for the job artifacts requests.

The job artifacts API returns a redirect to URL CDN/storage, but in middleware this is not treated as a success:

def call(env)
  response = @app.call(env)

  # We only log authorizations leading to successful requests.
  Ci::JobToken::Authorization.log_captures_async if success?(response[0])

  response
end

private

def success?(status)
  (200..299).cover?(status)
end
