Typescript support for playwright config

[fmquaglia]

I'm running the demo SevlteKit app. When I try to run the test suite using the configuration I get this error:

contexts of ./playwright.congif.ts

import type { PlaywrightTestConfig } from '@playwright/test';

const config: PlaywrightTestConfig = {
    webServer: {
        command: 'npm run build && npm run preview',
        port: 4173
    },
    testDir: 'tests'
};

export default config;

hi Fabricio! Are you able to run this example from the command line? If yes, what's the difference in the command?
