[Docs] Enhance Video Sections in Layer5 Docs by Adding Transcripts

#### Current Behavior

Currently, the videos section in the Layer5 documentation only has the videos. There are no written transcripts available for users who prefer reading or need accessibility support.

https://docs.layer5.io/videos/


#### Desired Behavior

Add a transcript below each video.
This transcript should have
- TItle
- Duration
- Naration
- Links etc

It will make it easier for users to quickly read the content, improve accessibility, and enhance user experience.

#### Implementation

#### Acceptance Tests

#### Mockups
