fix(nextjs): Fix Http integration type declaration (#10338)

For some reason `const { Http: OriginalHttp } = Integrations` caused
weirdness around getting type imports from the local build structure
instead of importing the type top-level. This patch removes the object
destructuring in favour of directly referencing `Integrations.Http`.
