Add manage links to scope edit admin pages for certain scope links
## Problem
On certain scope plugin admin pages, e.g.
/admin/config/ai/context/settings/scope/language
/admin/config/ai/context/settings/scope/tag
You can enable/disable the scope plugin but not see the "manage link", e.g.
"Manage Languages"
"Manage Tags"
Yet if you adding/editing a context item, you do see those links.
## Solution
If the manage link is not the same as the scope admin page link, then add a link to it.
Example:
"Manage Site Sections" => /admin/config/ai/context/settings/scope/site-section
is the same as the scope admin page so don't add it because it would be self-referential.
"Manage Languages" => /admin/config/regional/language
is not the same as the scope admin page so add it.
