fix: added @sentry/profiling-node to sep list to prevent build/bundle breakage (#60855)
Issue: https://github.com/vercel/next.js/issues/60853
### What?
Added `@sentry/profiling-node` to the server-external-package object so
that sentry users who want to use this package don't have to manually
add this package in the experimental nextjs config entry.
### Why?
Package bundling will fail as shown in the following issue if not added
to this exclude list.
