Allow Keybind Exclusivity in Task Assignment

[PedroBT03]

⚬ PROBLEM:
The YouTube extension currently allows users to assign the same keybind to multiple tasks simultaneously, which can potentially lead to conflicts and confusion among users.

⚬ SOLUTION:
Introduce a feature that enables keybind exclusivity when assigning tasks. When a user selects a keybind for a particular task, the extension should prompt a dialog for confirmation before removing that keybind from any other tasks to prevent conflicts.

⚬ ALTERNATIVES:
I thought in two options:

• A dialog prompt for confirmation before removing the keybind from other tasks.
• Automatic removal of the keybind from other tasks without a confirmation dialog.

⚬ RELEVANCE / SCOPE:
This feature enhancement would benefit all users who utilize shortcuts, as it enhances clarity and reduces potential conflicts in task assignment.

⚬ SIDE EFFECTS:
I don't think that implementing this feature introduce conflicts or adverse effects.

⚬ CONTEXT:
This behavior aligns with common practices observed in many sites and applications, where the same keybind is typically not allowed to be assigned to multiple functions simultaneously.
