📝 (reflectedworkitemid.md): add redirect for /server-configuration/ to improve navigation

Add a new redirect from /server-configuration/ to the existing
documentation page for ReflectedWorkItemId. This change enhances
user experience by ensuring that users looking for server
configuration information are directed to relevant content,
thereby reducing potential confusion and improving documentation
accessibility.

 The Azure DevOps migrations Tools has no internal state, and uses a field on the work item to track the migration of work items. This field is always referd to in the docs as `ReflectedWorkItemId` and is used to track the work item in the target. It enables the ability to resume migrations as well as to be able to scope the work items based on a query and have multiple runs overlap.
