Fixed touchdevice not autorotating after hyprland update

Overview:

This pull request fixes a small bug where after updating to hyprland v0.37.x, the autorotation of touchinput is not working after rotating monitor device with iio-hyprland.

Problem:

After updating hyprland, the Touch Devices are not being rotated on my 2-in-1. Executing iio-hyprland shows the following output:

ok
config option <device:wacom-hid-5215-pen:transform> does not exist.
config option <device:wacom-hid-5215-finger:transform> does not exist.

Cause:

Now, hyprland's default behaviour is assigning the digitizer rotation value automatically when the monitor rotation changes. Thanks to this PR: https://github.com/hyprwm/Hyprland/pull/3544 Therefore Hyprland's config for changing touchdevice rotation is changed in v0.37.0 Now to rotate touchdevice, the config entry looks like this (from hyprland wiki v0.37.0):

input {
    touchdevice {
        transform = 1
    }
}

Changes Made:

Added appropriate command based on new config changes instead of manually looping through all devices since, hyprland automatically does it now.

Testing Done:

Tested the fix on Lenovo IdeaPad Flex 5 14ALC05 and autorotation of touchdevice works correctly as intended.
