Dirga Yuza f2361469e4 hwdb: add force-release to Nitro AN515-58 backlight keys
This fixes an incomplete mapping introduced in PR #39769 for the Acer
Nitro 5 AN515-58.

The previous PR mapped the physical keyboard backlight keys (scancodes
`0xef` and `0xf0`) to `kbdillumup` and `kbdillumdown` to prevent them
from dropping screen brightness.

However, the embedded controller on this Acer model only emits "make"
(press) scancodes and fails to emit "break" (release) scancodes for
these specific keys. Without a release event, the input subsystem
registers the keys as continously held down (auto-repeat). In desktop
environments like KDE Plasma, pressing the key once causes the
brightness UI slider to get stuck in an infinite adjustment loop.

This issue is previously unnoticed as this model did not expose any
keyboard backlight control.

The fix is done by prepending the `!` (force-release) flag to the
keycodes. This instructs `evdev` to synthesize a key
release event.

The fix is verified locally on an Acer Nitro AN515-58. `evtest` now
correctly reports `value 1` immediately followed by `value` 0, and KDE
Plasma brightness OSD no longer gets stuck.
