Build completely broken in codespaces now.

Hello,

I have a codespace build of nextjs, and vite from the codespaces templates
and neither of them work out of the box due to https issues. I'm not sure if the hosting domain for the port forwarded sites has changed, but using .dev means the browser is forced to connect using https and I am pretty sure that neither nextjs or vite are configured to use https which causes ssl issues.

If I load the codespace into my local vs code instance and start the vite/nextjs instance there I can connect just fine. So I imagine for these templates to work again either:

1) Don't serve these port forwarded instances from a .dev domain so developers can connect to them via http
2) Update these templates to work for a https connection and make that a default since .dev domains can only be connected to via https

### Simple Browser
### Normal Browser (see SSL error)

まず Codespaces Next.js および Vite テンプレートで問題を再現し、ポートフォワーディングされた URL が HTTPS をどのように処理するかを調査します。両方のテンプレートが Codespaces から起動し、転送されたサイトが HTTP 経由または動作する HTTPS 設定によって SSL エラーなしで読み込まれれば完了です。
