fix: Resolve App details image duplications

Description

The user uploads one image on the App details page while registering the app but it ended up showing the same image 3 times. Since max 3 images can be uploaded, the system somehow repeats the image thrice.
One single image repeat thrice on the Validate & Publish screen as well as on the App overview page.

Image should display only once on both the Validate & Publish screen as well as on the App overview page.
