Update VideoPlayer2.tsx

[Aryam2121]

Tracks the current video index using the currentVideoIndex state variable. Accepts a list of videos as input (videoList) and uses currentVideoIndex to determine the current video. When a video ends, it checks whether there is a next video. If there is, it automatically plays the next video using handleVideoEnded. Adds a button that appears when there is a next video in the list. When clicked, it advances to the next video in the list. ////////////// I add a button for next video for enhancement for user go to next video issue #384
