Add translate Japanese! I'll change it again if I find any mistakes.

Hey @Miku-i Thank you for the PR! I spoke with you on Discord about this.
Since .org is a fork of the .io repo, it defaults to the Upstream repo for TarkovTracker.io that isn't actively maintained.
If possible can you open a PR using tarkovtracker-org/TarkovTracker and master branch as the "Base" with your repo as the Head Repository and the correct branch then it will properly target the .org repo, after doing this I can then work on adding it!

(If I don't hear back I will manually transfer the translations to .org where it can be applied)
