Help/About: Add cache busting string to video thumbnail.

Append `?ver=6.0` to the image used for linking to the video to break the cache in browsers, proxy servers and on the CDN.

A new version of the image has been uploaded and replaced the file in the original location.

Props annezazu, critterverse, ryelle, costdev, ironprogrammer, dd32.
Fixes #55808.
