Fix global nav after redirect add
Issue Description
The MR at gitlab!46573 (merged) changes https://docs.gitlab.com/ee/development/sidekiq_debugging.html
to have a proper redirect to https://docs.gitlab.com/ee/administration/troubleshooting/sidekiq.html
. The existing page, however, has a global nav entry as Contributor > GitLab Development style guides > Sidekiq debugging
that needs to be updated.
