Library is inconsistent with its documentation and some methods just do not work

This does not work either:

gh_api.get_content("Ark-kun", "pipeline_components", "/components/XGBoost/Train/component.yaml", "47f3621344c884666a926c8a15d77562f1cc5e0a")

TypeError: get_content() takes 2 positional arguments but 5 were given

Parameters:

help(gh_api.get_content)
# get_content(path) method of ghapi.core.GhApi instance

but in documentation:
