docs(README): correct spanish translation errors in .es.md

[dignodev]

¡Hola! Soy hablante nativo de español y he notado algunos errores en la traducción del README. He corregido:

• Errores ortográficos (tildes, acentuación)
• Términos técnicos mal traducidos
• Mejorado la fluidez y claridad

Los cambios son solo de texto, no afectan el código. ¿Podrían revisarlos?

Description

This PR fixes grammar, spelling, and consistency issues in the Spanish translation of the README.es.md file. The changes include accent corrections, proper tildes usage, grammatical agreement, and appropriate Spanish technical terminology.

Changes Made

• Spelling corrections:

  • "interfáz" → "interfaz" (correct according to RAE - Royal Spanish Academy)
  • "liberación" → "versión" (context-appropriate translation)
  • "antigüas" → "antiguas"
  • "pudiera" → "podrá" (verb tense correction)

• Grammar fixes:

  • Added missing period at end of sentences
  • Gender/number agreement: "menú" (singular) vs "menus" → "menús"
  • Preposition corrections: "basado en" → "está basado en"

• Standardized technical terms:

  • "Dialog" → "Diálogo" (consistent Spanish translation)
  • "Patrocinantes" → "Patrocinadores"
  • "LEEME" → "README" (keeping English technical term)
  • Removed unnecessary anglicisms

• Clarity improvements:

  • "Aplicacones" → "aplicaciones"
  • "de mucha ayuda" → "de ayuda" (more natural Spanish)
  • "2017-presente" → "2017-Hoy" (more common format)

Type of Change

• Documentation fix (non-breaking change)
