Add support for fastify 5

[notaphplover]

fastify@5 is released 😃.

@as-integrations/fastify peerDependencies include fastify@^4.4.0. Please consider releasing a new version supporting fastify@5.

Thanks for the heads up! Should be able to start on this soon.

Any news about this ?

I'm joining the crowd wishing for a swift resolution to this. Considering there's two open pr's trying to solve the same thing I hope the maintainers push for one of them soon.

I see, should we fork the repo, merge the PR and publish it under another org? It's been a while since I opened the issue

@olyop @trevor-scheer Could you please take a gander at the two prs?

Any update on this? I'm stuck on my Fastify/Nest server updates as well due to this.
