fix: compatibility for vercel adapter

[Aslemammad]

Does this fix the issue completely?

[Loshido]

it has fixed my case, however i had to change a path in adapters\vercel-edge\vite.config.ts

// [...]
export default extendConfig(baseConfig, () => {
  return {
    build: {
      // [...]
+       outDir: ".vercel/output/static",
-       outDir: ".vercel/output/functions/_qwik-city.func",
    },
    plugins: [vercelEdgeAdapter()],
  };
});

it builds correctly

Actually we can close the pr, with further debugging i found that there was no issue in this rep, i just did not configure correctly. I was supposed to change ´outDir´ in the qwikVite plugin's option. It didn't work when i tried before the creation of the issue because there is an already existing issue in the vercel adapter that made me thought the issue was in this rep. this issue
