[Issue]: Why do we keep the highest community level？

[kShines]

Describe the issue

I think we should keep the community id list, not the level Since the community id is required later in calculating the report weight, the level does not seem to make sense

    entity_df = cast(pd.DataFrame, entity_df[["title", "degree", "community", "level"]]).rename(
        columns={"title": "name", "degree": "rank"}
    )

    entity_df["community"] = entity_df["community"].fillna(-1)
    entity_df["community"] = entity_df["community"].astype(int)
    entity_df["rank"] = entity_df["rank"].astype(int)

    # for duplicate entities, keep the one with the highest community level
    entity_df["community"] = entity_df["community"].apply(lambda x: str(x))
    entity_df = (
        entity_df.groupby(["name", "rank"])
        .agg({"community": lambda x: list(x)})
        .reset_index()
    )
