Issue

When Django ORM triggers a database query and generates corresponding OTel client span, the client span contains wrong code attributes:

  "code.function.name": "django.db.backends.utils.CursorDebugWrapper._execute",
  "code.file.path": "/usr/local/lib/python3.10/site-packages/django/db/backends/utils.py",
  "db.query.text": "SELECT \"billing_service_billing\".\"id\", \"billing_service_billing\".\"owner_id\", \"billing_service_billing\".\"type\", \"billing_service_billing\".\"type_name\", \"billing_service_billing\".\"pet_id\", \"billing_service_billing\".\"payment\", \"billing_service_billing\".\"status\" FROM \"billing_service_billing\" WHERE NOT (\"billing_service_billing\".\"type_name\" IN (SELECT DISTINCT U0.\"invalid_name\" AS \"invalid_name\" FROM \"check_list\" U0 LIMIT 100)) LIMIT 3810",

Function name django.db.backends.utils.CursorDebugWrapper._execute and file path /usr/local/lib/python3.10/site-packages/django/db/backends/utils.py are from Django, not user code.

Description of changes

The root cause is django distribute name is Django(Distribution(name='Django', version='5.2.7')), does not match with the package name django.
The bug can be fixed by using a case-insensitive string comparison.

Testing

After fix:

"attributes": {
        "code.function.name": "views.orm_example_view",
        "code.file.path": "/Volumes/workplace/extension/aws-otel-python-instrumentation/samples/django/views.py",
        "code.line.number": 278,
        "db.system": "sqlite",
        "db.name": "",
        "db.statement": "SELECT \"auth_user\".\"id\", \"auth_user\".\"password\", \"auth_user\".\"last_login\", \"auth_user\".\"is_superuser\", \"auth_user\".\"username\", \"auth_user\".\"first_name\", \"auth_user\".\"last_name\", \"auth_user\".\"email\", \"auth_user\".\"is_staff\", \"auth_user\".\"is_active\", \"auth_user\".\"date_joined\" FROM \"auth_user\" WHERE \"auth_user\".\"is_active\" LIMIT 10"
    },
