[FIX] website_slides: Complete courses with video

What are the steps to reproduce your issue ?

    1. Install ELearning
    2. Create a course
    3. Add a video from youtube
    4. Attempt to do the course from a user that is invited

What is currently happening ?

    You cannot complete a video (turn the checkmark green) if there is not a quiz. Therefore you cannot complete the course

What are you expecting to happen ?

    Turn the checkmark green to signify that video is completed after watching the video and then have the ability to complete the course

Why is this happening ?

    Because of this commit https://github.com/odoo/odoo/pull/61581/files
    that changes 'youtube.com' to 'youtube-nocookie.com'

How to fix the bug ?

    Remove host
