chore: Update litep2p to v0.8.2

[lexnv]

This includes a critical fix for debug release versions of litep2p (which are running in Kusama as validators).

While at it, have stopped the oncall pain of alerts around incoming_connections_total. We can rethink the metric expose of litep2p in Q1.

[0.8.2] - 2024-11-27

This release ensures that the provided peer identity is verified at the crypto/noise protocol level, enhancing security and preventing potential misuses.
The release also includes a fix that caused TransportService component to panic on debug builds.

Fixed

• req-resp: Fix panic on connection closed for substream open failure (#291)
• crypto/noise: Verify crypto/noise signature payload (#278)

Changed

• transport_service/logs: Provide less details for trace logs (#292)

Testing Done

This has been extensively tested in Kusama on all validators, that are now running litep2p.

Deployed PR: #6638

Litep2p Dashboards

Libp2p vs Litep2p CPU usage

After deploying litep2p we have reduced CPU usage from around 300-400% to 200%, this is a significant boost in performance, freeing resources for other subcomponents to function more optimally.
