Add websocket subscriptions example to fastify integration

[rmortes]

Hi. I'm currently using pothos + graphql-yoga + fastify in my server, and it's been working great. I'm currently developing a feature that requires subscriptions. The default SSE subscriptions work out of the box, but I can't use this protocol since my client doesn't support it.

I'd like to see the fastify example expanded with support for websocket subscriptions.

Thanks

Checkout our example using graphql-ws https://github.com/dotansimha/graphql-yoga/blob/master/examples/graphql-ws/src/index.ts

Hi saihaj! Thanks for answering me so quickly.

I'm afraid that example was the first I tried replicating, but I can't figure out how to make it work with fastify
