Use http server instead of express

[mildronize]

• Reducing dependencies between azure function adapter and express plugins
• explicit use of dev mode like Next.js custom server

see https://nextjs.org/docs/pages/building-your-application/configuring/custom-server

Expected Behavior

import { createServer } from 'node:http';
const dev = process.env.NODE_ENV !== 'production'

// when using middleware `hostname` and `port` must be provided below
const app = nammatham({ dev, hostname, port })

I think we can deprecated the main role of packages @nammatham/express, Previously, as a main server for azure functions dev
