cargo: Update litep2p to v0.12.3 (#10665)

## [0.12.3] - 2025-12-16

This release improves the robustness of the multistream-select
negotiation over WebRTC transport and fixes inbound bandwidth metering
on substreams. It also enhances the dialing success rate by improving
the transport dialing logic. Additionally, it re-exports CID's multihash
to facilitate the construction of CID V1.

### Changed

- transports: Improves the robustness and success rate of connection
dialing ([#495](paritytech/litep2p#495))
- types: Re-export cid's multihash to construct CID V1
([#491](paritytech/litep2p#491))

### Fixed

- fix: multistream-select negotiation on outbound substream over webrtc
([#465](paritytech/litep2p#465))
- substream: Fix inbound bandwidth metering
([#499](paritytech/litep2p#499))
