Problem

Specifying "unstable": ["otel"] in deno.json does not enable otel signals while specifying --unstable-otel in the run command does.

A similar issue was raised in #27273 but otel enabling was since refactored in #27333 so I believe this is a different problem.

Expected behavior

both "unstable": ["otel"] and --unstable otel should work to trigger the otel unstable feature flag

Actual behavior

"unstable": ["otel"] does not seem to do anything while --unstable otel works.

Environment

Deno v2.3.3
