docs(v2): removed duplicate text under "Using React" section

[booshnelli]

Motivation

duplicate text found in "Using React" section of creating-pages doc. very tiny fix.
as its very small, perhaps expand this section or remove entirely and put these sentences elsewhere?

You will have to edit the docs within website/docs as well. The problem exists on the trunk version of docs - https://deploy-preview-3201--docusaurus-2.netlify.app/build/docs/next/creating-pages
