Unnecessary reply usage

[pkulcsarnr]

Based on the official documentation, in case of async / await usage there is no need to use the reply.send() syntax.

Previous syntax
fastify.get('/', (request, reply) => { reply.send({ hello: 'world' }) })
New syntax:
fastify.get('/', async (request, reply) => { return { hello: 'world' } })
