Refine list of tokens available for staff slip templates

Story: There are several tokens that are important for staff to be able to use on hold and transit slips. It allows them to better understand all the details regarding an item. For example, which item is supposed to be held or transited, where it's going, where it's coming from, who requested it, where they are expecting to pick it up, or when it's hold expires or the request expires.

Context: Hold and transit slips have already been built in FOLIO. Hold slips are used to place a requested item on the hold shelf while they are awaiting pickup. Transit slips are used to either transit an item to its home location or its requested location. Paging request slips are a third type of slip that will be built soon - https://issues.folio.org/browse/UXPROD-1280, and they require the same list of tokens.

Scenarios:

1. Scenario
   • Given edit mode for a Hold or Transit staff slip template (Settings > Circulation > Staff Slips)
   • When the curly braces icon (for inserting a new token) are clicked in the rich text editor
   • Then the tokens listed in the table above should be available via the insert token modal
     • See visual for order and layout
2. Scenario
   • Given view mode or edit mode for a Hold or Transit staff slip template (Settings > Circulation > Staff Slips)
   • When preview is clicked
   • Then the placeholder text for preview listed in the table above should be displayed instead of the token label with curly braces
     • For example, Smith instead of {requester.lastName}
3. Scenario
   • Given a scan event (check) with a prompt to print a Hold or Transit staff slip
   • When staff slip is printed (or previewed from print dialog)
   • Then the real values for each token for the specific item scanned should be printed on the slip (along with any other copy)
