Variable naming inconsistency in the tutorial documentation

Hi,
I have just used the React tutorial, it is great!
It helps a lot to learn the basic.

While working, I have spotted a small inconsistency on https://github.com/reactjs/reactjs.org/blob/main/content/tutorial/tutorial.md

When creating the buttons to move into the history, we are using a move variable that we are sending to jumpTo:

But jumpTo use step to make the moves:

I suggest that we switch the move and step variables of the render function to make the tutorial more understandable by beginners:

I can push a merge request for the documentation but I do not know how to change the source code linked by @gaearon on codepen:
https://codepen.io/gaearon/pen/gWWZgR?editors=0010

Is there a way to do that?

content/tutorial/tutorial.md から始め、チュートリアルの render 関数を jumpTo と併せて読み、変数名の一貫性の欠如を確認します。リンクされた CodePen も要求されたドキュメント変更の対象かどうかを確認します。チュートリアルで一貫した名前が使われ、該当する例が初心者にも理解しやすい状態になれば完了です。
