higher image quality, tweak webp hint

[mal-tee]

• the tweaked hint gets rid of the weird lines in, e.g. this image
  • UPDATE: seems like that didn't do the trick
• the higher quality (default is 75) gets rid of some compression artifacts, but comes with a slight size increase
  • 15% or 0.77 KB for my test thumbnail in my local build
  • 22% or 5.94KB for the same image in big

"Fix transparency problem when converting 32-bit images to WebP 8f40f34c @bep #8729"

I'm definitely on board with changing the hint and updating Hugo. The size increase for the thumbnails is also ok with me.

As for the regular images, that is a more significant increase (especially in absolute terms, which matters more imo). I just did a little non-scientific blind test trying to guess which of the versions is the "better" one and while I can see small differences, I was genuinely wrong more than half of the time…

I'll let @zner0L decide whether we want to crank up the quality.

I agree, its not that important for most images. Maybe in the future I will just add an option for higher quality to some thumbnails.

Thank you!
