Already had one actually, but looks like the font was a bit off versus the one you've added. Once tests pass will merge and update with the new image.

I did not notice that there was one already, I'll check my code again and remove these files in this PR as well.

The 'old' one we orginally have is under docs/images/nf-core_eager_socialmediatemplate.svg, you can remove that and I'll update with your new (I assume consistent with the rest of nf-core) one.

Ping me once ready!

@jfy133 Files removed.
The main issue was that the image had a transparent background (which doesn't work good in nightmode).
The size of the logo and fonts was slightly off, but that was less important.

Image updated in settings too 👍

[maxulysse]

Wasn't it up to date already?

[jfy133]

Uhhh maybe? It seemed to change when I did it? But maybe that was a wierd flickering bug. All good anyway!
