Fix grammar in Refactoring documentation (#9525)

This PR fixes a grammatical error in the Refactoring documentation.

Change:

→ "so that you can reuse the code elsewhere"

This improves readability and corrects the sentence without changing its meaning.

 Refactorings are provided by a language service. VS Code has built-in support for TypeScript and JavaScript refactoring through the [TypeScript](https://www.typescriptlang.org/) language service. Refactoring support for other programming languages is enabled through VS Code [extensions](/docs/configure/extensions/extension-marketplace.md) that contribute language services.
