[Feature Request] Add Spanish Translation to IoTAtlas

[pabloariasmora]

Description:
The current documentation is available in English, Chinese, and French. It would be beneficial to add a Spanish translation to make the documentation more accessible to Spanish-speaking users.

Proposed Solution:

• Translate the existing documentation into Spanish.
• Ensure that the Spanish version is kept up-to-date with any changes to the English, Chinese, and French versions.

Benefits:

• Increased accessibility for Spanish-speaking users.
• Broader reach and inclusivity for the project.

I have completed the translation of all documentation files to Spanish and have the code ready for a pull request. I am available to work on this and submit the pull request at your convenience.

Please let me know how you would like to proceed.

Thank you!
