Nuxt dev server with https is broken on Node 18+

[Atinux]

Reproduction:

npx nuxi init@latest my-app
cd my-app
pnpm i
npx nuxi dev --https

I also notice that we don't support the devServer.https: true option, any reason for that?

Actually the devServer.https: true option works but display a TS error:

If you are experiencing this, you can downgrade to Node v16 or use legacy devBundler. For now, it seems that our SSL vite-node solution is not compatible with Node 18+ with native fetch.

nuxt/packages/vite/src/runtime/vite-node-shared.mjs

Lines 6 to 11 in b49f2a8

	export const viteNodeFetch = $fetch.create({
	baseURL: viteNodeOptions.baseURL,
	agent: viteNodeOptions.baseURL.startsWith('https://')
	? new HTTPSAgent({ rejectUnauthorized: false })
	: null
	})

This is now working for me.

Worth to mention, the final fix for this is that Nuxi CLI uses an internal http server + public https server which proxies to the internal one and vite dev server directly uses internal server.

In case of using --https --no-fork, we would need some Node.js flags to allow unauthorized keys (written in CLI output log)
