Server running in worker mode doesn't have health

Bug report

Describe the bug

When medusa server is running in workerMode: "worker" it runs http server but doesn't setup health entrypoint.
We use this entrypoint in kubernetes readiness check.

health route is skipped in worker mode in loadEntrypoints method.

This is expected behavior, as worker processes do not load application entry points, including the HTTP layer. You will need to perform your readiness check differently for the worker processes. I am not very familiar with Kubernetes and their readiness probes, so I am not sure what is possible, but perhaps you can instead write a script that opens a (very) short-lived socket connection to the worker process to evaluate its health.

It's just the whole purpose of the merged PR #6790 was to enable http server to serve health endpoint.
So worker runs http server now but it's useless =)
