[BUGFIX] Correct link variable in record title in EXT:linkvalidator

With #103493 a new link was introduced to edit the full record that
contains a broken link. In doing so, the existing link variable was
renamed, which caused the link stored on the record title to no longer
work. This patch now sets the correct variable for this link again.
