docs: Fix links in the documentation

A couple of internal links use `#toc_4` to attempt to locate a document
element within another document page. In both of these instances, there
is no element on the linked to pages with the id `#toc_4`. This commit
updates those links with the document elements which were the original
intended links, meaning these links now take you directly to the
intended element.
