### Feature Description

Currently, only F1-F12 are recognized and can be bound to actions.

_No response_

### Proposed Solution

I think we need to update quickshell/Widgets/KeybindItem.qml.

### Alternatives/Existing Solutions

_No response_

Start by reading quickshell/Widgets/KeybindItem.qml, where the issue says keybindings should be updated. Check how the existing F1-F12 names are recognized, then verify that F13-F24 can be bound to actions across all compositors.
