Depends on #6762
This PR removes pinyin conversion (eg 中国 => ["zhong", "guo"]) in our new multilingual tokenizer implementation. This fixes Chinese stopwords, because the tokens were in pinyin but our stopword list is written with Chinese letters (so basically we did
assert!(["是", "上去", ...].contains("shì")))Since Pinyin is just the romanized phonetic version of a Chinese word, we can use the original Chinese word without loosing information about the word. We even improve precision, because multiple Chinese words can map to the same Pinyin, e.g. 忘记 and 旺季 is both
["wang", "ji"](https://www.quora.com/Is-pinyin-romanization-a-bijective-map).
