Agent doesn't work with Git inside a Node.js script using a SSH + SSO key on GitHub

Okay so: regular git operations within the affected repos work fine with the default configuration but running git inside the provided simple Node script still fails randomly.

The deploy script we use at work basically does this

```ts
import {exec} from 'child_process';

(async () => {
exec('git rev-parse ....', {cwd: process.cwd()}, () => {
exec('git fetch ...', {cwd: process.cwd()}, () => {
exec('git log ...', {cwd: process.cwd()}, () => {
exec('git push origin foo:bar', {cwd: process.cwd()}, console.log);
});
});
});
})();
```

So I'll run into situations where the git fetch succeeds but not the final git push, or vice versa or sometimes everything will work or sometimes nothing will. I'm starting to think that when it works it's "by accident" because I can't figure out a clear pattern 😞
