typo in 'create a new react app' page

[hapumee]

I'm so sorry to mention about this, but the page 'create-a-new-react-app.html' doesn't show up whole contents of it on Chrome and IE also. (Part of the contents show up on the page)
I think that it's because of script tag(<script>) below.

It might be translated "<script>" tag instead of " `<script>` " text, so the browser treats it as a HTML tag.

• https://ko.reactjs.org/docs/create-a-new-react-app.html

• PR create-a-new-react-app.md Translation  #64 (line 25)

I think that it's better to modify that. ^^;
