Move all images to webp

[notthetup]

webp image format provides improved loading time and performance compared to jpg and with the upcoming update to Safari it will be supported by most browsers https://caniuse.com/?search=webp

We should consider moving to webp.

The cleanest approach is to build an asset pipeline for all our assets so we can "transform" them as needed (compress, scale, convert to file format etc)

Once we have this asset pipeline, we can resuse it in various places.
