[FIX] base: update Spanish states
[FIX] base: update Spanish states

According official country source (BOE) some states changed their denomination
to allocate local language spelling.
https://www.boe.es/diario_boe/txt.php?id=BOE-A-2011-11606

As there's a lot of people that still uses the old one, the best solution is to
include both words in the name of the state, and thus user can search by any of
them.

"Melilla" code is also incorrect according used nomenclature but can not be
modified in stable version.
Futher commit can correct it with a migration script

Closes #15166
