add japanese translate

Hi all.

I wanna advocate this manifesto and principle of Extensible Web to Japanese web devs.

I think this thought is quite important for web future, so I wanna join this as possible as I can.
in japan, there are lots of powerful web developer, but it seem for me that they don't no about this manifesto well.
at first, I translate this in Japanese. but I don't know how publish it.

so I create this PR for asking you.

if it's works fine for you, I'm appreciate it if you publish this for example at https://ja.extensiblewebmanifesto.org/ 
or if that dosen't works. please let me to publish this at my own domain (https://jxck.io) or on my blog (http://jxck.hatenablog.com).

also, thanks for your every works for web.

thanks, and sorry for my poor english ;p

I thought there was a consistent Japanese translation for "security surface area" (like 関数 for function), and then we could find appropriate words around it (like 適用 for apply, 束縛 for bind, ...).

However It seems not. This document uses "セキュリティ領域" as "security surface area".

But another document just uses "セキュリティの問題" for the word, even in the same company.

How about "新しいセキュリティの問題を減らすことができます"? It can be translated as "Reduce new security problems", but it is not so far from the original paragraph.
