[BUG] brightness widget doesn't update based hyprland keybindings

[nergdron]

Describe the bug
I've got a hyprland keybinding config that adjusts the brightness of my laptop monitor using brightnessctl, but I've noticed the brightness widget in my top nwg-panel never seems to pick up these changes caused by something external to it.

it's doubly odd because running the same commands in my shell does result in the widget picking it up, so there's probably some interaction here that I don't understand. no clue why running commands in a terminal would produce different results than those run directly by hyprland.

To Reproduce

1. set a hyprland key binding to brightnessctl set 5%-
2. press the key you bound
3. see that the brightness of your display decreases, but the brightness widget doesn't get updated with the new value

Expected behavior
expect the state of the widget to sync with the screen state, like it does when running brightnessctl from a terminal.

Desktop (please complete the following information):

• EndeavourOS (arch variant)
• hyprland 0.43.0-1
• nwg-panel version 0.9.39

Can't confirm. Works as expected on my side.
