image resizing (legacy) to resize images stored on R2 on-the-fly, which is pretty cheap (1$ per 50.000), but it is deprecated and changed to Cloudflare images transform, which cost 25x more (1$ per 50.000 vs 1$ per 2.000).Sourcing kit but it's not working, only S3 is supported, Can anyone help me to point out how to do the migration?
