Skins: update preview images for LateNight 64 sampler skins

[ywwg]

fixes: #11763

[ronso0]

Thanks.
Why 4k images? The previews are 640x360 (1280x720 with 200%) and can't be zoomed. I don't thnk we need that extra 1 MB here.

Those need to be in LateNight (64 Samplers) ; )

I can shrink them more if you want

Yes, please use 1920x1080, it's just the ratio (16:9) matches that of the preview label
The images of this PR are all 1920:1200, therefore the preferences label won't use the available width

Lines 355 to 358 in 0bc192c

	skinPreviewLabel->setPixmap(preview.scaled(
	QSize(640, 360) * m_dDevicePixelRatio,
	Qt::KeepAspectRatio,
	Qt::SmoothTransformation));

[ronso0]
