Allow the enter key to start a new checkout session

Background
In mid-October 2021, Holly was asked by Cornell University Library to review various issues discovered by CUL Access Services staff while using FOLIO. Holly met with various individuals at Olin and Mann libraries and produced the CORNELL ACCESS SERVICES FOLIO OBSERVATIONS & SUGGESTIONS document, which is available at https://docs.google.com/document/d/1lwnZpkiw7G0c3EyObRRnjuV6XVMcFNK1lWUG952sFgI/edit?usp=sharing. This feature is ISSUE #8 from that document and has a priority of NOT AS IMPORTANT.

Overview
When checking out a batch of items for transit, it is difficult to process a pile of books quickly when the user has to click on the END SESSION button every time. It would be helpful to allow the ENTER key to clear the session as well.
