Maybe very important!!! Fix embedding error

[billvsme]

The asyncio.as_completed() function does not guarantee that the results are ordered

When using this project, I found that the entities and relationships of the recall were somewhat related to the low-level keywords and the high-level keyword, but it was not very related, and I felt that the ability of the vector model was not fully utilized, it maybe a strange problem.

I looked at the code of inserting vectors and found problem. asyncio.as_completed is used incorrectly, asyncio.as_completed results are not returned in the order in input tasks, but in the order in which the tasks were completed. I changed to use asyncio.gather to make sure the results were orderly. And ensure that tqdm works properly.

This code need asyncio.as_completed results were orderly

	if len(embeddings) == len(list_data):
	for i, d in enumerate(list_data):
	d["__vector__"] = embeddings[i]
