Add multilingual support

to do - Decouple english docs from main website

motivation- For adding translation support for spanish, french and other languages in the future

Look at the website's file structure to find where English documentation is currently embedded. Identify the main HTML, CSS, and JavaScript files that render the docs. The goal is to separate these text strings into a separate file or module, likely JSON or a similar format, to prepare for future translations. Check if there are any existing examples of string extraction in the project.
