This PR refines various Spanish localization strings to ensure they read naturally and accurately for Spanish-speaking users.

More Natural Wording

• We replaced certain words or phrases to better match common Spanish usage.
  • “Tamaño de la ventana” instead of “Tamaño de ventana”
  • Esta opción no es compatible con tu sistema operativo” instead of “Esta opción no está soportada por tu sistema operativo”

Grammatical Improvements

• Certain sentences were revised to use the subjunctive after “asegúrate de que…,” which is standard in Spanish for expressing conditions or possibilities.

• Passive voice construction was standardized, resulting in more natural Spanish equivalents.
  • “se instalará” instead of “será instalado a…
