Added difficulty level for Synonym Finder

I’m excited to share that I’ve added a new feature to the Synonym Finder in my word game! Players can now select their difficulty level before they start playing. This feature lets players pick a level that matches their English ability, whether they’re just starting out or already know it well.

I added this feature because I noticed some players found the game too hard, while others thought it was too easy. I wanted everyone to have a fun experience, so now users can choose the level that suits them best. The goal is to make the game more flexible and allow players to learn at a pace that works for them.
