Update storage-format-(linux).md for kernel 5.7+ users

[CatKasha]

Kernel 5.7 got native exFAT support and new tools to manage it, exfatprogs Also did some testing and dd is not required, mkfs.exfat (both exfatprogs and exfat-utils) wipe all partitions and make correct exFAT fs on the sdcard if you point mkfs.exfat to a physical device (tested on Ubuntu 24.04 and 18.04.6)

And note about -s 128K for exfat-utils, idk why its format with double less cluster size (i only have 32gb sdcard and 64gb usb drive, so i cant test it with larger one), thats why is 128KB
