feature: auto scroll to the week when sidebar is opened

[Chityalaakhil]

I always had to scroll to the bottom of the sidebar to select next video whenever I'm watching week 28, 29, etc videos. Instead of that, when I select a week and open the sidebar, the sidebar should automatically scroll to the week accordion and expand the accordion.

Describe the solution you'd like
Sidebar should auto scroll to the current selected week accordion and expand accordion.
