Review comment (suggestion):
Now we can use the `_build_url_result` method I suggested above:
```suggestion
            yield self._build_url_result(episode)
```

Code after:
    IE_NAME = 'nebula:season'
    _VALID_URL = rf'{_BASE_URL_RE}/(?P<series>[\w-]+)/season/(?P<season_number>\d+)'
    _TESTS = [{
        'url': 'https://nebula.tv/jetlag/season/15',
        'info_dict': {
            'id': 'jetlag_15',
            'title': 'Tag: All Stars',
            'description': 'md5:5aa5b8abf3de71756448dc44ffebb674',
        },
        'playlist_count': 8,
    }, {
        'url': 'https://nebula.tv/jetlag/season/14',
        'info_dict': {
            'id': 'jetlag_14',
