LP2052960 Remove button markup from record actions
Removes errant <button> elements that were nested inside the Patron View
and Place Hold links (in the bib record actions row of buttons below the
summary box). Buttons inside links are unnecessary and created an extra
tab stop when navigating the page via keyboard. Classes have been moved
to the <a> element to retain styling.
Release-note: Remove extra tab stops when navigating bib record actions in staff client using keyboard
