[FEATURE] Implement Keyboard Shortcut to Delete Drawing on Screen

[yashmandi]

Feature Description
I have worked with similar drawing sites, and when I draw something and I want to delete / erase something, I have the habit of selecting it by mouse and delete / erase it using 'DELETE' button on my keyboard. This feature would be helpful for many people.

*Solution
When someone wants to delete / erase the drawing, they can simply select it using mouse and press delete button on keyboard.
I would like to work on this issue under GSSoC '24, request you to assign this task to me :)
