docs: update and improve Readme.md in Spanish

Restore the comprehensive Spanish version of the `Readme.md` and add a new section with instructions for installing the Meslo font, which is required for the `oh-my-posh` theme to render correctly.

The new section is located in the "Troubleshooting" area and provides the necessary command (`oh-my-posh font install meslo`) to ensure a correct setup.

The rest of the document has been reviewed to ensure it is complete and accurately reflects the script's functionality.
