update target and module options tsconfig.json

The target version has also been changed from `ESNext` to `ES2021`
because we need to ensure that we only use features that are supported
by the Node.js version that is bundled with VS Code. Node.js 20.x
supports all ES2021 features.

The module options have also been updated to stop typescript from
enforcing unexpected module resolution rules.
