Use the SVG logo or a higher resolution PNG

This is actually, beacuse I downloaded the SVG and converted it to a PNG and manually copied it to the directory, because the actual image in this repository seems to be corrupted and doesn't work. So that this is pixelated is more on my side.

The real problem here is, that the provided image in this repository doesn't work anymore, as can also be seen when following the link.

So this issue should moreso be called:

Replace current image by working codecheck_logo.png or codecheck_logo.svg
