refactor(fs): use node:fs, drop fs-extra in copyFiles.ts #5761

## Problem
Eliminate fs-extra from the codebase.

## Solution
We can use `fs.cp` since node v16.7.0+.
Note that `overwrite` is now `force` based on
https://nodejs.org/api/fs.html#fscpsyncsrc-dest-options

Bump the dependency @types/node to avoid casting (fs as any).
