fix: prevent double slashes in image URLs from getImageUrl()

[SaitejaKommi]

Description

The getImageUrl() function produces URLs with double slashes (e.g., /assets//image.png) when the assets path ends with /.

Current Behavior

assetsImagesPath.set("/assets/")
getImageUrl("logo.png") // Returns "/assets//logo.png" ❌

Expected Behavior :

assetsImagesPath.set("/assets/")
getImageUrl("logo.png") // Should return "/assets/logo.png" ✅
