Reviewer's Guide

This patch reverts the manual relocation of the ImagePreviewer DOM element by removing both the appendChild call in init and the element removal in dispose, ensuring the preview component remains within its original container (fixes #7059).

Pull Request Overview

This PR removes unnecessary DOM manipulation from the ImagePreviewer component by eliminating manual element append and removal operations. Since the ImagePreviewer element is already managed by Blazor's rendering system, these JavaScript operations were redundant and potentially problematic.

• Removed manual DOM element appending in the init function
• Removed manual DOM element removal in the dispose function
• Updated version numbers for both Visual Studio 17.0 and 18.0 builds
