fix: Download IGDB screenshots with right aspect ratio

[adamantike]

The IGDB API provides screenshots in 720p resolution, when either screenshot_huge or 720p size values are used [1]. The screenshot_huge uses Lfill, while 720p uses Fit as the resizing method.

That means that either screenshot_huge or 720p will provide the correct aspect ratio for 16:9 platforms. However, for platforms with a different aspect ratio, we need to use the 720p size value to get the correct image instead of a cropped one.

Example:

• screenshot_huge
• 720p
