backport2509: cargo: Update yamux to 0.13.8 to avoid panics (#10479)

This PR updates rust-yamux to 0.13.8 from 0.13.6:
- #9169

This aims at not polling sockets past the point they return errors and
effectively avoids panics when tungstenite websocket connections are
used in combination with rust-yamux.


The fix was backported on 2512 but not on 2509
