udev: Use arch linux wiki zram rules
from: https://wiki.archlinux.org/title/Zram#Optimizing%20swap%20on%20zram
"Explanation of the configuration:
These values are what Pop!_OS uses. That Pop!_OS GitHub pull request also links to some testing done by users on r/Fedora, which determined that vm.page-cluster = 0 is ideal. They also found a high swappiness value to be ideal, which matches what is suggested by the kernel docs:
The default value is 60.
For in-memory swap, like zram or zswap, as well as hybrid setups that have swap on faster devices than the filesystem, values beyond 100 can be considered. For example, if the random IO against the swap device is on average 2x faster than IO from the filesystem, swappiness should be 133 (x + 2x = 200, 2x = 133.33).
On a system with a hard drive, random I/O against the zswap device would be orders of magnitude faster than I/O against the filesystem, so swappiness should be ~200. Even on a system with a fast SSD, a high swappiness value may be ideal." - Arch Wiki
The zram rules are handled here: https://github.com/CachyOS/CachyOS-Settings/blob/master/usr/lib/udev/rules.d/30-zram.rules
The reason for this, is to only apply the changes, when zram is found.

thank you, i has added in this file 30-zram.rules
