Examples in Django doc doesn't work out of the box

[nitz-uglabs]

Describe your environment

OS: Arch Linux, up to date
Python version: Python 3.12.6
SDK version: 1.27.0
API version: 1.27.0

What happened?

Following the examples in the docs, the autoinstrumentation on Django is not sufficient to cause data to be sent to STDOUT, as the docs claim would happen

Steps to Reproduce

mkdir /tmp/bob
cd /tmp/bob
virtualenv venv
venv/bin/pip install django opentelemetry-instrumentation-django opentelemetry-sdk requests
venv/bin/django-admin startproject mysite

Then edited mysite to insert:

#!/usr/bin/env python
"""Django's command-line utility for administrative tasks."""
import os
import sys
from opentelemetry.instrumentation.django import DjangoInstrumentor # NEW
def main():
    """Run administrative tasks."""
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'mysite.settings')
    DjangoInstrumentor().instrument() # NEW
...

Run the site:

venv/bin/python mysite/manage.py runserver

View localhost:8000 on the browser, curl it, etc. The only thing that shows up:

Watching for file changes with StatReloader

Expected Result

something like the docs say:

{
    "name": "home_page_view",
    "context": {
        "trace_id": "0xed88755c56d95d05a506f5f70e7849b9",
        "span_id": "0x0a94c7a60e0650d5",
        "trace_state": "{}"
    },
    "kind": "SpanKind.SERVER",
    "parent_id": "0x3096ef92e621c22d",
    "start_time": "2020-04-26T01:49:57.205833Z",
    "end_time": "2020-04-26T01:49:57.206214Z",
    "status": {
        "status_code": "OK"
    },
    "attributes": {
        "http.request.method": "GET",
        "server.address": "localhost",
        "url.scheme": "http",
        "server.port": 8000,
        "url.full": "http://localhost:8000/?param=hello",
        "server.socket.address": "127.0.0.1",
        "network.protocol.version": "1.1",
        "http.response.status_code": 200
    },
    "events": [],
    "links": []
}

Actual Result

No fancy open telemetry output, as the docs claim.

Additional context

#4125 indicates that there's something possibly missing in the docs, and that the auto-instrumentor works.
While this is possible and I'll try that later this week, I was hoping to not have to modify the execution command and instead do the manage.py modification.

Happy to put some work into this, but I'd like to first confirm that I'm not doing something silly

Would you like to implement a fix?

Yes
