migrate to cjs

[Eomm]

We should consider to migrate to cjm.

Right now:

const app = require('fastify')({ logger: true })
app.register(require('fastify-orama'))
app.get('/', async (request, reply) => {
  return { hello: 'world' }
})
app.post('/', async (request, reply) => {
  return request.body
})
app.listen({ port: 8080 })

Triggers:

/Users/mspigolon/workspace/_experiments/asd/asd.js:2
app.register(require('fastify-orama'))
             ^

Error [ERR_REQUIRE_ESM]: require() of ES Module /Users/mspigolon/workspace/_experiments/asd/node_modules/fastify-orama/index.js from /Users/mspigolon/workspace/_experiments/asd/asd.js not supported.
Instead change the require of index.js in /Users/mspigolon/workspace/_experiments/asd/asd.js to a dynamic import() which is available in all CommonJS modules.
    at Object.<anonymous> (/Users/mspigolon/workspace/_experiments/asd/asd.js:2:14) {
  code: 'ERR_REQUIRE_ESM'
}

Instead, working with cjs - it works with both cjs and esm without any issues.
