In https://gitlab.com/gitlab-org/gitlab-foss/-/merge_requests/17883, we
added a feature that would allow a project export to be uploaded and
imported successfully before deleting the old copy of the project.

This overwrite feature would always check whether the user had owner
privileges in the group of the project. If the user only had maintainer
privileges or less--even if an overwrite was not happening--the
import/export would fail with an empty `Projects::ImportService::Error`.

To fix this, we make two changes:

1. Only do the permission check if we actually need to overwrite
the project.
2. If the permission check fails, raise an exception with details.

This MR splits the reference architecture page into a main page
(index.md) and seven child pages, one per size of reference
architecture. It copies the footnotes over to each child page, and
removes them from the main page. It also adds an unordered list of
the child pages to the main page, and each of the child pages has
an introductory sentence that links back to the main page.
