chore: Update litep2p to v0.8.2 (#6677)

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](https://github.com/paritytech/litep2p/pull/291))
- crypto/noise: Verify crypto/noise signature payload
([#278](https://github.com/paritytech/litep2p/pull/278))

### Changed

- transport_service/logs: Provide less details for trace logs
([#292](https://github.com/paritytech/litep2p/pull/292))


## Testing Done

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

### 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.
