Add Best of 5 Mode to Rock Paper Scissors Game

[NikkG-300]

Description:
Currently, the game runs infinitely To make it more engaging and competitive, we can implement a "Best of 5" gameplay mode where the first to 3 wins is declared the overall winner and which can also improve the overall effect of the game as well

Proposed Solution:
Track total rounds played and wins.
Stop the game after either player reaches 3 wins, or after 5 total rounds.
Display the overall winner message.
Reset or prompt user to restart for better use

Benefits:
Makes the game more structured
Encourages repeat plays and competition and so on

I've implemented the "Best of 5 Mode" for the Rock Paper Scissors game as requested in this issue. The new mode allows players to compete over 5 rounds, with the winner being the first to win 3 rounds. I've tested it for various scenarios (e.g., player wins 3, computer wins 3, tie after 5) and ensured compatibility with existing features like score tracking and quitting with 'Q'.
