Caps Lock cannot be bound as a usable key

[purple4pur]

When caps lock is on, raylib's isKeyDown(capslock) always return true, which is not expected.

Example code:

minigame-raylib/speedtest/speedtest.zig

Lines 497 to 500 in d4b793f

	if (isBindingDown(k1Binding)) {
	k1BgProp.color = rl.Color.gold;
	try k1Bar.pressed();
	} else {

minigame-raylib/speedtest/speedtest.zig

Line 513 in d4b793f

if (isBindingPressed(k1Binding)) try kps.catchKeyAt(time);
