fix atom exhaustion quiz

[cocoa-xu]

• The original quiz ignores the cases that livebook or other GenServers can create new atoms while we're running the quiz, hence it may show false even if the correct solution is provided (see the screenshot below)
• Makes it really random by generating a UUIDv4 string,
• Simply put the true feedback in the catch branch to avoid using atom count, since it's expected to raise an error

Seems that there are some spelling issues from main after resolving conflicts, I'll send the fix in another PR => #83
