jupyter_server: Exceptions when spawning process(es) with `multiprocessing`

Description

Running code that relies on spawning new processes with the multiprocessing library raises exceptions during runpy.run_path. This was initially discovered when running a Dask-CUDA cluster that spawns workers as multiple processes and is commonly used in Jupyter. Such errors are also minimally reproducible using multiprocessing only.

Rolling back several versions, I could not reproduce the error on jupyter_server=1.18.1, but jupyter_server=1.19.1 and above would already reproduce variations of the same error. For example, with jupyter_server=2.0.0:

Reproduce

Start a docker miniconda3 docker container (optional, baremetal will reproduce the error too): docker run -t -i -p 8888:8888 continuumio/miniconda3 /bin/bash
Create a new conda environment with Jupyter only: conda create -n jlab-test --override-channels --strict-channel-priority -c conda-forge -c nodefaults jupyterlab;
Activate environment: conda activate jlab-test;
Start JupyterLab: jupyter-lab --ip=0.0.0.0 --port=8888 --no-browser --allow-root (--allow-root should be skipped if not running on docker);
Connect to JupyterLab;
Create new notebook;
Paste the snippet (see below) in first cell;
Save;
Run cell (Shift+Enter).

import multiprocessing as mp
import time

p = mp.get_context("spawn").Process(target=time.sleep, args=(10,))
p.start()

Expected behavior

Spawning processes with multiprocessing should pass successfully without exceptions in runpy.run_path(...).

Context
