The changes in this commit were made to translate the website's text content from French to English, as part of efforts to ensure the platform is more accessible to a wider audience. This includes translation of user-facing instructions, button labels, form fields, and messages across multiple templates including home.html, setup1.html, setup2.html, and login.html among others.
