fix(cspell): whitelist Spanish words from installation docs page

The Spanish installation summary merged in #23 introduced 12 cspell
errors on main. Add the words to the repository dictionary following
the existing mixed-language pattern in .cspell.json.

Also normalize the unicode escape for 'extraída' to a literal UTF-8
character (semantically identical JSON).
