Minor typo in Step 1 of React tutorial docs

[sonejah21]

Detailed description

I noticed a minor typo in the tutorial docs today.

It says "used" when it should be "using" or "that use" in the following call out sentence:
Note: you can find a description of the different components used UI Shell in our [@carbon/react](https://github.com/carbon-design-system/carbon/tree/main/packages/react/src/components/UIShell) package.

Is this a feature request (new component, new icon), a bug, or a general issue? Bug

Steps to reproduce the issue

1. Step one: Head to https://carbondesignsystem.com/developing/react-tutorial/step-1/
2. Step two: Scroll down to the "Import and export the header" section
3. Step three: See the light blue box with the above sentence.
