Remove writing vscode config (#49133)

## What?

Removes writing the `.vscode/settings.json` config. This config is
needed in order to leverage the new Next.js TypeScript plugin.
What we'll do instead is add a message in the docs on how to enable it.
We'll also explore a VSCode extension that warns when you don't have the
TypeScript plugin set up.

## How?

Removed the code related to writing `.vscode`.


Closes #42213
