Feature: #99011 - Allow descriptions for redirects

Description

A new field description has been added to the sys_redirect table.

In the backend edit form, the new field is located under the Notes tab. It can be used to add context to the corresponding redirect. Since the field is defined as the record's descriptionColumn, the added information is also displayed in the "Record information" info box above the edit form, like known from e.g. content elements or pages.

Impact

It is now possible to add additional information to a redirect using the new description field, whose value is also displayed in the corresponding backend edit form.
