Update ProductPageVideos.html

Updated the injected "<video>" tags so that the video plays on Chrome Android.

On Android, autoplay is turned off and controls must be enabled via controls="controls" in order for the video to play at all.

On iOS, a similar behavior of the <video> HTML5 tag, except also the video must be full-screened.
