Synchronize versions of playwright-driver.browsers and npm package

I found a solution in Replace npm deps with nix deps - #3 by tobiasBora via

  postInstall = ''
    rm -rf node_modules/playwright
    ln -s ${playwright-driver} node_modules/playwright
    cp -r node_modules $out/lib
  '';

note sure if it is the recommended solution but it seems to work without heavy patches.
