001-keyboard.1m.sh & 001-mouse.1m.sh on newer M1 mac

Nobody has claimed this yet.

These scripts didn't work for me on OSX Monterey with M1 but the commands used in https://github.com/aromig/scripts/tree/master/check_battery worked fine.

I altered my scripts so they work and look like the following. I just wanted to share here in case anyone else had this issue.

### 001-keyboard.1m.sh
```sh
#!/bin/sh

# Keybard Battery
# Mat Ryer
# matryer

PERCENTAGE=$(ioreg -c AppleDeviceManagementHIDEventService -r -l | grep -i keyboard -A 20 | grep BatteryPercent | cut -d = -f2 | cut -d ' ' -f2)

if [ "$PERCENTAGE" ]; then
echo "⌨️ $PERCENTAGE%"
#else
# echo "without bluetooth keyboard?"
fi
```

### 001-mouse.1m.sh
```sh
#!/bin/sh
# Mouse battery
# 1.0
# Alexandre Espinosa Menor
# alexandregz
# Show battery percentage for Bluetooth Mouse
# http://i.imgur.com/IqjZMJg.png

# works fine with Magic Mouse

PERCENTAGE=$(ioreg -c AppleDeviceManagementHIDEventService -r -l | grep -i mouse -A 20 | grep BatteryPercent | cut -d = -f2 | cut -d ' ' -f2)

if [ "$PERCENTAGE" ]; then
echo "🖱️ $PERCENTAGE%"
#else
# echo "without bluetooth mouse?"
fi
```

Start with 001-keyboard.1m.sh and 001-mouse.1m.sh, then compare their battery lookup commands with the ioreg pipeline shown in the issue. Verify the updated scripts on an M1 Mac running Monterey and confirm that each plugin reports the connected device's battery percentage.
