The reason we had to revert jupyterhub#3228 was that the image cache was growing big, and so was the buildkit cache. So this meant images were being stored in *three* places: 1. the buildkit cache (dind) 2. the image cache (dind) 3. the containerd store (by kubernetes, when it pulls) 1 and 2 were both set to about 300, so this caused the disk to fill up. Here, I more aggressively prune the image cache, as it is simply not used when buildkit is used. Once I verify this works ok, I'll turn on buildkit building again and we see how it goes.

When we aren't using disk on the host for anything else, kubernetes can simply use as much of the disk as it wants for caching images. The default for this is upto 85%. However, since we *do* use the disk for our dind, we want to tune this to take up only half that size. I've already applied this to the 2i2c-hetzner node Follow-up to jupyterhub#3229
