fix(fastify): mark fastify as optional peer dependency

[dinwwwh]

Marks fastify as an optional peer dependency of @standardserver/fastify via peerDependenciesMeta. Package managers no longer warn about a missing peer or auto-install fastify for consumers who don't have it, while the >=5.6.1 range still applies whenever fastify is present.
