VS Code 1.88 doesn't support ESM extensions

[AlexCannonball]

Type: Bug

1. Make an extension code to use ESM instead of CJS. Set "type": "module" in the extension's package.json file.
2. Launch this extension via VS Code "Run and Debug".
3. Get an error upon the extension activation:

Activating extension 'xxxxxx' failed: require() of ES Module d:\xxxxxx\out\extension.js from d:\Programs\VS_code\resources\app\out\vs\loader.js not supported. Instead change the require of extension.js in d:\Programs\VS_code\resources\app\out\vs\loader.js to a dynamic import() which is available in all CommonJS modules..
