Fix Plugins dropping to native page after activating a plugin (v2.7.2)

Unlike Posts/Pages/Media/Users/Comments, Plugins only ever had its
sidebar link rewritten (MenuSerializer.php) — there was no
redirect_native_pages() case for direct visits to plugins.php itself.
WordPress's own post-activate/post-install redirect
(wp_redirect(self_admin_url('plugins.php?activate=true'))) is exactly
that: a direct visit with no ?page= param, landing on the true native
page until the sidebar link was clicked again.

Added the missing case, gated by modern_plugins like the others,
redirecting to plugins.php?page=aurora-admin-plugins to match the URL
the sidebar link itself already uses.

Verified live by visiting plugins.php?activate=true directly (the
exact URL WP's own redirect produces) — now lands on the Aurora page
correctly, confirmed with FileBird Lite showing Active in the list.
