Fixes ability to run `NODE_OPTIONS='--inspect' next dev` as described in
[docs](https://nextjs.org/docs/pages/building-your-application/configuring/debugging),
by removing inspect option from NODE_OPTIONS arg passed to worker
process.
This bug seem to have been introduced in
7d93808c43 as a part of a some
refactoring. See how `getNodeOptionsWithoutInspect` is no longer used.
Fixes#55862
