[CLIENT] Little typo in the spells page

Hey I just noticed a small typo on the Clarity page in the client. i'm guessing it comes from when you removed the spell from SR, you left the comma that was following ''Classic'' in ''Supported game modes: Classic, ARAM''

Steps to repeat:

1. Log into Client
2. Go to Spells tab
3. Read ''Supported game modes'' section

Thanks!
