Support for Fastify 3

[StarpTech]

Hi, the current plugin doesn't support fastify 3.

Reproduction: Follow https://github.com/apollographql/apollo-server/tree/main/packages/apollo-server-fastify

On server start:

 (node:18586) [FSTDEP003] FastifyDeprecation: You are using the legacy Content Type Parser function signature. Use the one suggested in the documentation instead.
(Use `node --trace-warnings ...` to show where the warning was created)
🚀 Server ready at http://localhost:4000/graphql
(node:18586) [FSTDEP001] FastifyDeprecation: You are accessing the Node.js core request object via "request.req", Use "request.raw" instead.

Response when calling the playground: GET query missing.

There are some open issues but it looks like that there is no progress. What's the current status?

This is fixed on the release-3.0 branch. Apollo Server 3.0 is now under active development; I hope to get some alphas out within a week.

Could you point to the test?

Hi @glasser, did you consider adding "fastify": "^2" as a peer dependency of apollo-server-fastify? It would save a lot of time spent trying to figure out why it doesn't work after upgrading the project's dependencies.

I hope you mean ^3?

That makes sense. I want to make sure I understand the choices we've made in our existing integration libraries about deps vs peer deps and am checking in with folks who worked on this project before me.
