[Feature]: The custom set language feature

• I have checked the repository for duplicate issues.

What feature do you want to see added?

Maybe there should be a need to add the custom set language feature in the config file?

Why do you want to have this feature?

Wii U only has Japanese, American and European versions. And it has not been sold in China and South Korea. If the app follows the machine, the Chinese and Korean translations will never be seen.

Any other details to share? (OPTIONAL)

This seems like a fine addition. @ashquarky any objections? We could keep the default behavior as it is now, taking in the system language, while also allowing users to override this

I s'pose. I'll note that the user will have to be able to navigate the menu enough to find the language selector, but if that's acceptable, we can do it.
