feat: Japanese translation for docs

[yoshi2no]

Changes

ref: #1815

• fix: correct link to LICENSE (en, zh)
• fix: correct link to openapi-fetch, Enable noUncheckedIndexedAccess in TSConfig (en, zh)
• add vitepress ja config
• translate openapi-typescript
• translate openapi-fetch
• translate openapi-react-query

I believe there shouldn’t be any content missing from the latest documents since I’m referring to the most up-to-date version.

How to Review

• language code is correct
  • ja, 日本語
• It should redirect to version 6.x of the English documentation when using version 6.x with the Japanese language specified
• Ensure the "search docs" is working
  • Is there anything I need to do to enable this for the Japanese docs?

Thank you so much for opening! Re: search, that’s all automatic! Algolia scans the published site on its own, so there’s nothing to do on our end. Yes there is a slight delay before Japenese docs would appear in search yes but not long (~1 day)

Is it OK if I push an empty commit to
this PR? That’ll create a preview link on Cloudflare Pages to test out

@drwpow

ok! yes please!

This is the fix for the invalid link mentioned in the Changes same for zh doc.

Oh shoot it’s not the developer permissions; it’s that Cloudflare just doesn’t deploy previews for forks at all 🤔. My commit didn’t do anything. I’ve just always assumed.

Anyway, made a docs preview to inspect: https://ja-preview.openapi-ts.pages.dev/

Overall, the dev version is pretty reliable! But just in case others wanted to inspect it easily too. (Also to check Cloudflare didn’t have a build error)

This looks amazing! Great work with this, thank you! 🙏 Skimming through the pages, they seem good to me (minus me not being able to read Japanese). Docs all seem to be working well.

But let me know when you’re ready to merge this! This looks good from my end. After merge, I’ll trigger a manual reindex from Algolia so that appears in search as soon as possible.

Thank you for the review!
After taking another quick look, everything seems good to me as well. Let’s go ahead and merge it! 🚀

As a native Japanese speaker, thank you and great work @yoshi2no! I took a look the diff and the preview quickly and could not find any issues for now. I would like to review Japanese docs if needed, so feel free to mention me if you are finding a reviewer for that!

I’ll definitely mention you if I need a reviewer in the future!
