📚 Description
Resolved an issue where images could load more than once in the NuxtImg component. Previously, when a placeholder image was in use, it triggered a new image load even though the main image had already started loading. The update ensures that if a placeholder is already handled, we avoid loading the image again. This change prevents duplicate network requests and avoids unnecessary load events. By removing the preload using new image() instance and adding onLoad to imgAttrs, and using vue reactive to handle the update when placeholderLoaded is true
