Development server not starting when GVZ API not reachable
### Describe the Bug
<!-- A clear and concise description of what the bug is. -->
When the [GVZ API](http://gvz.integreat-app.de/api/search/expect_empty_json) is reachable, but does not answer, the development server hangs during start, because there is no timeout defined for the api request [here](https://github.com/Integreat/cms-django/blob/f4f4c698575e975655b1333f630b5f0d6e4e034f/src/gvz_api/apps.py#L27).

### Steps to Reproduce

1. Execute `./dev-tools/run.sh` when GVZ API is reachable but does not answer (tested this morning)
2. Wait

### Expected Behavior
<!-- A clear and concise description of what you expected to happen. -->
The server should start and print a log message that the gvz api is not available

### Actual Behavior
<!-- A clear and concise description of what actually happened. -->
The server does not start

### Additional Information
<!-- Add any other context (e.g. logs, screenshots, etc.) about the problem here. -->
