[Bug]: [BiliBili] 下载B站分part视频时报错：KeyError: 'id' #817
Description
Prerequisites
- I have searched existing issues and discussions to ensure this bug hasn't been reported before
- I have read the troubleshooting section in the README
- I have tested this issue with yt-dlp directly (not just through MeTube UI) as described in the README
- I have checked that this is not a yt-dlp issue (if it is, please report it to yt-dlp repository instead)
Bug Description
尽管 #552 中提到过这个问题并且该issue提示已经解决了，但我测试了一下还是有bug， 看起来报错的位置并不相同。下载B站分part视频的时候，如果设置Strict Playlist Mode模式，只能下载到一个视频，如果不设置，就会报错：

~~~~~^^^^^^
KeyError: 'id'经测试上述错误仅在分part视频中出现，合集时可以正常下载的。 我调试了一下发现是没有正确处理id这个键，一个绕过的方法是在遍历entry的时候强制加上id：
async def __add_entry(self, entry, quality, format, folder, custom_name_prefix, playlist_strict_mode, playlist_item_limit, auto_start, already):
...
elif etype == 'playlist':
log.debug('Processing as a playlist')
entries = entry['entries']
log.info(f'playlist detected with {len(entries)} entries')
playlist_index_digits = len(str(len(entries)))
results = []
if playlist_item_limit > 0:
log.info(f'Playlist item limit is set. Processing only first {playlist_item_limit} entries')
entries = entries[:playlist_item_limit]
for index, etr in enumerate(entries, start=1):
etr["_type"] = "video"
etr['id'] = etr.get('id', entry['id']) # 👈👈👈 如果没有列表元素没有id，使用列表本身的id报错的视频是 https://www.bilibili.com/video/BV1g3411z72f，实测加上最后这一行后可以下载了。
不过美中不足是，实际上还是没有解决分p视频解析中的id/title问题，导致webUI没有正确显示每个part的标题，而是id。
