mercurius-js / mercurius

documentation is federation.md:

Lines 27 to 29 in cbe637d

    
           const Fastify = require('fastify') 
        
           const mercuriusWithFederation = require('@mercuriusjs/federation')

is incorrect it should be:

const { mercuriusFederationPlugin } = require('@mercuriusjs/federation')
or we should fix the export on mercurius-federation and export it as default:
https://github.com/mercurius-js/mercurius-federation/blob/26894effa137bb4c6e8ae21b9b3247345b906245/index.js#L2-L6

also to keep consistency between plugins (gateway has default export)

I would fix mercurius-federation.

	const Fastify = require('fastify')
	const mercuriusWithFederation = require('@mercuriusjs/federation')
