fix(nextjs): Export Replay from index.server.ts to avoid TS error (#…

…6577)

This patch fixes a TypeScript error when using the `Replay` integration exported from the NextJS SDK (>= 7.27.0). Because our SDK tells TS that it should import types from `index.server.ts`, TS doesn't find the Replay integration class although it's correctly exported from `indext.client.ts`. 

Note: even without this change, Replay works in NextJS, it just fixes just a TS error.
