[Docs] Duplicate Video Thumbnails on Getting Started Page

[zihanKuang]

Current State

On the [Getting Started Videos page](https://docs.layer5.io/videos/getting-started), the same video thumbnail and description ("Design Reviews: Adding Comments") are repeated multiple times.This makes it difficult for users to identify different video content and appears to be a UI or content duplication issue.

Screenshot for reference:

hey @zihanKuang I would like to work on this issue

They're all essentially the same video, multiple videos were added so that #437 can be added.

Makes sense @vr-varad .
If you'd take a look at the linked pr to the issue #437, it seems to be abandoned. It'd be much helpful if you can step in and help move that pr forward. Feel free to open a new pr with your changes, if you do.

yeah sure @vishalvivekm I will look into it and make a pr soon
