Latin American Spanish: Change "Hecho" to "Listo" to match iOS 18.4

[juanarzola]

Fixes

Tested In iOS 18.4:

• Spanish (Latin American) translation of "Done" is "Listo" instead of "Hecho" on all Apple apps.
  • This also feels natural to me because you'd rarely say "Hecho" when something is done, "Hecho" needs the verb "Está hecho". It's common to say "Listo" on its own.
• Spanish (Spain)'s translation of "Done" is still "OK".

Proposed Changes

• Replace "Hecho" with "Listo" in Spanish (Latin America).
