##### SUMMARY
Hi,

When you want to pass an empty list or a null/None value to published_ports on docker_container it's actually impossible, so you get this error

```
File \"/tmp/ansible_docker_container_payload_ZOZc5l/__main__.py\", line 1448, in _parse_publish_ports\r\n  File \"/tmp/ansible_docker_container_payload_ZOZc5l/__main__.py\", line 1003, in parse_port_range\r\nValueError: invalid literal for int() with base 10: ''\r\n",
 ```

Ref #61602

The problem is that we parse via `_parse_publish_ports` the parameter if self.published_ports is not None or not 'all'
Also after that there is no control on each elements of the list, (not like for the volumes parameter by example)

So I propose to patch line 1151
`self.published_ports = self._parse_publish_ports() `
to
`self.published_ports = self._parse_publish_ports() if self.published_ports else None`

Best regards
