fix: Resolve App details image duplications

[ss-nikunj]

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.

Why

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

Issue

• Shared Component: #288
• Portal Frontend: #1031

Hi @oyo, As per your suggestions, I have removed the changelog entry and the redundant else statement from the code. Can you please review it again?

Thank you! 😊
