[JA] translate home

[tequdev]

• The part of card.description that is a JSX.Element instead of a string cannot be translated.
• Links in the page will redirect to the English page.

We will need to make changes to transition to the correct language.

Maybe useI18n can be used.

const { lang } = useI18n();
console.log(lang) // ja, en-US

Ready to merge when conflicts are resolved.
