Release 0.1.2

Changed:

• Default language Vietnamese to English
• Fix main.py
• Fix language.py #F*CK GEMINI
• Fix shop_menu.py

Therefore, all the files have been fixed, I'll update the downloaded file later. .
If you ask: Why did you delete release version 0.1.0? And why version 0.1.2? Where is version 0.1.1?
Me: I accidentally deleted the 0.1.0 version and I like to jump straight to 0.1.1 (like iPhone 8 -> iPhone X).
