[FEATURE REQUEST] Thumbnail view of the package to be installed

Please confirm these before moving forward.

• I have searched for my feature proposal and have not found a work-in-progress/duplicate/resolved/discarded issue.
• This proposal is a completely new feature. If you want to suggest an improvement or an enhancement, please use this template.

Describe the new feature

UniGetUi does not currently have a feature to display thumbnails of the packages to be installed; this is important because an image can give a more general idea of ​​the software to be installed.

Describe how this new feature could help users

When selecting a package, right-clicking and choosing "Package Details" from the UniGetUI pop-up menu displays a window with package details, including one or more software thumbnails.

I propose keeping this functionality, but also opening a banner below the packages with general details of the software to be installed, including one or more thumbnails, when a package is selected. If no package is selected, this banner should be hidden.

I've attached a couple of screenshots: the first shows the current view of UniGetUI, and the second shows how this feature could be implemented.
