Typos and mistakes in tutorial

[mikelyou]

Hi, during my translation work, I found two possible typos or mistakes in the tutorial.

• It seems that How to contribute? on the homepage cannot be translated, is it a deliberate design or a mistake?
• It said in the strikeTokensTutorialContent that ...and cost you 1 strike token.... Maybe it should be "add" rather than "cost" since players have 0 trike tokens at the game starts and have 3 when the game fails.
