Outdated link to alertmanager.html at Prometheus Alertmanager section of gitlab.rb
Problem to solve
I intend to enable alertmanager in my gitlab instance. Prometheus Alertmanager section of
/etc/gitlab/gitlab.rb file point to the documentation at https://docs.gitlab.com/ce/administration/monitoring/prometheus/alertmanager.html, but this page doesn't exist.
gitlab.rb should point to the updated link or the current link should have its content created/moved back.
