Add Jenkins/Build Badge for upstream official image status

Problem

We often have people ask when why images or architectures are missing

Solution

Add a build badge or badges to the Official Images jenkins status of the Node.js jobs

Alternatives to Consider

Maybe having the build badges on the README would be confusing, because that date might end up on the Docker Hub, and maybe pointing to the links from the Issue Template picker might work instead.

まず Node.js image README と Issue Template picker を確認し、次に upstream Official Images の Jenkins jobs とその status links を調べます。Docker Hub metadata によって誤解を招くことなく、image と architecture の build status を最も適切に示せる場所を決めてください。選択した場所に、関連する Jenkins status にリンクする動作する badge または badges が含まれていれば完了です。
