The e2e test shows an update notification if a newer version is available (in packages/e2e-tests/test/e2e.spec.ts) does not see the update notification in the captured shell output when running under Node.js nightly (v26+). The local httpServer fixture serves the update payload as expected on stable Node, but the notification doesn't surface on nightly.

Likely related to changes in Node.js's HTTP/fetch implementation. Needs a closer look at how mongosh's update-fetch path interacts with the test's local httpServer under the nightly binary.

The test is currently skipped under process.version.includes('-nightly'). Investigate and re-enable.

Follow-up from MONGOSH-2969.
