fix: vscode launch file to debug celery tasks

[Gilbert09]

Problem

• Using the existing vscode launch config for celery didn't allow me to debug tasks, and workers would spontaneously fail

Changes

• Update the launch config with the same settings as what celery is loaded with in ./bin/start

How did you test this code?

• Run a task locally and debug it 🤓

I'm not using vscode, but here's a ✅ in case nobody else confirms this works in a reasonable amount of time. Not many people debug python via vscode.

It's been a long time since I used this, but looks good
