`to_bipartite_graph` documented return type is incorrect

[jg-you]

The docstring for xgi.to_bipartite_graph states that the function returns a bipartite graph directly: https://xgi.readthedocs.io/en/stable/api/convert.html?highlight=to_bipartite_graph#xgi.convert.to_bipartite_graph

But the function returns a triplet of a graph with two mappings, I think from integers to node / edges IDs? https://xgi.readthedocs.io/en/stable/_modules/xgi/convert.html#to_bipartite_graph
