Similar to #10742. Collection and global-level admin options are
currently documented within the "admin > collections" and "admin >
globals" pages, respectively. This makes them hard to find because
users, myself included, intuitively navigate to the collection and
global overview docs to locate this information before realizing it
lives elsewhere. Now, they are rendered within "configuration >
collections" and "configuration > globals" as expected and the old pages
have been removed altogether.
