Gunicorn throws error upon handling SIGINT

[PKizzle]

Describe the bug When sending a SIGINT to the authentik server gunicorn throws an error.

To Reproduce Steps to reproduce the behavior:

1. Start a shell inside an authentik Docker image
2. Run dumb-init -- /lifecycle/ak server and wait for the startup to finish successfully
3. Send a SIGINT to the process i.e. by using the keyboard (CTRL+c)
4. See error

Expected behavior The process should exit without throwing an error.
