Fixed wide image on shorts

[itsrn]

When the extension adds MrBeast to a short's thumbnail, it's way too wide: I tried to change the styling of the MrBeast image on the short thumbnail, and found the (I hope) perfect settings for it:

top: 123px;
left: -3px;
width: 160%;
height: 50%;
z-index: 0;

which turned the thumbnail to look now like this: which is way better then before. I modified the code so now it will show as this on shorts, and the normal settings on "normal" sized thumbnails.
