Bug 42454: Terminology: Use "and" instead of "&" for curbside pickups tab

The "Staged & ready (0)" tab for curbside pickups (Circulation > Holds
and bookings > Curbside pickup) should use "and" instead of "&".

See terminology guidelines for "& (ampersand)" - Only use "&" when part
of a proper noun or a common abbreviation,... Otherwise, use "and":

Test plan:
1. Enable the CurbsidePickup system preference.
2. Configure curbside pickup for Centerville:
   - Go to Administration > Patrons and circulation > Curbside pickup
   - Set values:
     . Enable: selected
     . Pickup interval: 5
     . Maximum patrons per interval: 1
     . Patron-scheduled pickup: selected
     . Enable for waiting holds only: selected
     . Curbside pickup hours: add from and to hours for some days
     . Click Save configuration
3. Go to Circulation > Holds and bookings > Curbside pickup.
4. Note that there is an '&' in the "Staged & ready (0)" tab title.
5. Apply the patch.
6. Refresh the page.
7. Note that and is spelt in full "Stage and ready (0)".
