feat(lyrics-plus/netease): normalize album name before comparing

Besides, in Spotify Taiwan, the album name is in Traditional
Chinese, which is not aligned with what NCM chooses. Therefore,
I have written a simple converter that converts the Traditional
Chinese album name to Simplified Chinese so that we can compare
the correct album name in such cases.
