[paolacernada]

Description

This pull request introduces a Spanish translation of the README file, alongside a language switcher to toggle between the English and Spanish versions. The following changes have been implemented:

Changes

• README Translation:

  • Created README.es.md to provide documentation in Spanish, improving accessibility for Spanish-speaking users.

• Language Switcher:

  • Added a language switcher at the top of both README.md and README.es.md. This switcher includes links for users to easily switch between the two languages, enhancing the usability and inclusiveness of the documentation.

Implementation Details

1. Translation of Documentation:

   • Translated all sections of the original README, ensuring that technical terms and instructions are accurately conveyed in Spanish.

2. HTML Language Switcher:

   • Implemented an HTML snippet at the beginning of both README files, allowing seamless switching between English and Spanish.

<div style="text-align: right;">
  <a href="README.md">English</a> | <a href="README.es.md">Español</a>
</div>

Benefits
