### Feature description

Currently, the default port range for external services is configured in `config.py` as follows:
https://github.com/localstack/localstack/blob/075a6fcfcc29af99e1997d73abea6e88351f3c84/localstack/config.py#L462-L472
This means that the default service range is: (4510,4540]
But the example `docker-compose.yml` states (4510, 4530):
https://github.com/localstack/localstack/blob/075a6fcfcc29af99e1997d73abea6e88351f3c84/docker-compose.yml#L12

The currently stated 20 ports can already be somewhat limiting if a lot of external services are started (f.e. lots of clusters or databases). Therefore the range should be broadened and correctly defined in our example `docker-compose.yml` file.

### 🧑‍💻 Implementation

- [x] Broaden the service port range to 50 ports.
- [x] Update the example docker-compose file.
