Update doctrine.yaml

I removed from `doctrine.yaml` code below because since Symfony 6.4, `profiling_collect_backtrace` is here : https://github.com/symfony/demo/blob/main/config/packages/doctrine.yaml#L9

```yaml
when@dev:
    doctrine:
        dbal:
            profiling_collect_backtrace: true
```
