Add GTQ - Guatamalan Quetzal currency (#23249)

## Reason

Thunes onboarding commences!
The first 2 countries we'll iterate on for the implementation are El Salvador and Guatemala, as they're both reasonably supported in the dev environment.

El Salvador is USD, which is convenient.  For Guatemala we'll need the Quetzal .

Fun fact about the Quetzal, the currency notes display their value in Mayan numerals in the top right corner
