Make Documentation/admin-guide/reporting-issues.rst point to the newly created document about regressions (Documentation/admin-guide/regressions-users.rst). This allows to shorten a few explanations the new document describes better and in more detail. While at it move the copyright hint to the end of the file, as suggested during review of the new documents about regressions.
