Customize Ordering of Rails Admin Navigation Sections

Problem

Review suggestion from https://gitlab.com/gitlab-org/customers-gitlab-com/-/merge_requests/13156:

Would it be possible to move the Trials section either before Provision Tracking or after Support sections?

It seems like the Trials section is almost at the bottom of the page and I believe these are pages that would be used on a more frequent basis than Provision tracking, right? This is just a personal opinion based on my own experience with using CDot every single hour 🙂

The Rails admin framework currently orders the pages contained within navigation sections in alphabetical order by default

This may not be ideal for our internal use cases where some sections are more frequently accessed than others, and could make for a better user experience if those are closer to the top of the navigation menu

Proposal

Introduce custom ordering to Rails admin navigation in CustomersDot. Consult with stakeholder teams such as Support to determine most frequently used sections, etc. which could help determine an ideal order of sorting.

We could potentially make use of the weighting feature offered by Rails admin to customize the ordering.
