Missing Information About env.VITE_LANGUAGES Structure

[yumenohosi]

Hello,

Thank you for sharing such great code!

While running the project, I noticed that the structure information for env.VITE_LANGUAGES is missing. Although I can infer some details from the code, it would be very helpful if you could share the setup instructions or structure for env.VITE_LANGUAGES to assist users.

Thank you for your support!
