[BUG] useHotkeys callback is missing hotkey

[ljani]

Describe the bug
According to the documentation, useHotkeys' callback should have a property called hotkey (see "Also you could work directly with hotkey trigger:"), but it disappeared with v5. This is working fine in v4.

hotkey property is very useful to distinguish between eg. shift+a and ctrl+a if there are lots of combinations in one callback (I'm using it for context menu with many, dynamic entries)

To Reproduce
Steps to reproduce the behavior:

1. Create a (TypeScript) project
2. Call:

useHotkeys(["ctrl+a", "shift+a"], (e, handler) => console.log(handler.hotkey));

Stackblitz: https://stackblitz.com/edit/vitejs-vite-qhkqevmj?file=src%2FApp.tsx

Actual behavior
undefined is logged

Expected behavior
Either ctrl+a or shift+a should be logged

Desktop (please complete the following information):

• Version: v5.1.0

Additional context

hotkey disappeared from parseHotkey between v4.6.2...v5.0.0
