This PR updates litep2p to version 0.9.1. The yamux config is entirely
removed to mirror the libp2p yamux upstream version.
While at it, I had to bump indexmap and URL as well. 


## [0.9.1] - 2025-01-19

This release enhances compatibility between litep2p and libp2p by using
the latest Yamux upstream version. Additionally, it includes various
improvements and fixes to boost the stability and performance of the
WebSocket stream and the multistream-select protocol.
