document jobservice.job_logger in configure-yml-file.md

The

https://goharbor.io/docs/2.11.0/install-config/configure-yml-file/
https://github.com/goharbor/website/blob/main/docs/install-config/configure-yml-file.md

does not mention

```
jobservice:
# The jobLoggers backend name, only support "STD_OUTPUT", "FILE" and/or "DB"
job_loggers:
- STD_OUTPUT
- FILE
```

and it seems to be a required configuration

```
sudo ./install.sh

So far undocumented but required/mandatory configuration parameters that I found
* `jobservice.logger_sweeper_duration`
* `jobservice.job_logger`
* `notification.webhook_job_http_client_timeout`

as a workaround one need to look into the the installer and look at the `harbor.yml.tmpl`
