feat(hotkeys): ✨ Overhaul hotkeys modal UI

[joshistoast]

Summary

The ability to customize hotkeys in invoke is great, unfortunately the UI of the implementation left much to be desired, so here's my revamp of the implementation as it stands.

Behavior Updates:

• Removes the need for an edit mode button by having an inline edit on each hotkey item.
• Removes the separate hot key edit component in favor of a small inline edit UI.

Added:

• Reset to defaults action requires confirmation first;
• More translations;
• Reset individual hotkeys to default;

Improved:

• Cached some functions outputs to prevent needless rerunning.

For some reason the ScrollableContent is starting at the bottom instead of the top. Haven't found the issue yet :(

Wrote and tested this on my linux machine. I'd appreciate if anyone could try this on macOS and/or Windows and gimme a 👍 if all is well. Talking specifically about modifier keys.
