chore: Release litep2p version 0.8.0 (#280)

## [0.8.0] - 2024-11-01

This release adds support for content provider advertisement and
discovery to Kademlia protocol implementation (see libp2p
[spec](https://github.com/libp2p/specs/blob/master/kad-dht/README.md#content-provider-advertisement-and-discovery)).
Additionally, the release includes several improvements and memory leak
fixes to enhance the stability and performance of the litep2p library.

### Added

- kad: Providers part 8: unit, e2e, and `libp2p` conformance tests
([#258](#258))
- kad: Providers part 7: better types and public API, public addresses &
known providers ([#246](#246))
- kad: Providers part 6: stop providing
([#245](#245))
- kad: Providers part 5: `GET_PROVIDERS` query
([#236](#236))
- kad: Providers part 4: refresh local providers
([#235](#235))
- kad: Providers part 3: publish provider records (start providing)
([#234](#234))

### Changed

- transport_service: Improve connection stability by downgrading
connections on substream inactivity
([#260](#260))
- transport: Abort canceled dial attempts for TCP, WebSocket and Quic
([#255](#255))
- kad/executor: Add timeout for writting frames
([#277](#277))
- kad: Avoid cloning the `KademliaMessage` and use reference for
`RoutingTable::closest`
([#233](#233))
- peer_state: Robust state machine transitions
([#251](#251))
- address_store: Improve address tracking and add eviction algorithm
([#250](#250))
- kad: Remove unused serde cfg
([#262](#262))
- req-resp: Refactor to move functionality to dedicated methods
([#244](#244))
- transport_service: Improve logs and move code from tokio::select macro
([#254](#254))

### Fixed

- tcp/websocket/quic: Fix cancel memory leak
([#272](#272))
- transport: Fix pending dials memory leak
([#271](#271))
- ping: Fix memory leak of unremoved `pending_opens`
([#274](#274))
- identify: Fix memory leak of unused `pending_opens`
([#273](#273))
- kad: Fix not retrieving local records
([#221](#221))

+### [Content Provider Advertisement and Discovery](https://github.com/paritytech/litep2p/pull/234)
+
+Litep2p now supports content provider advertisement and discovery through the Kademlia protocol.
+Content providers can publish their records to the network, and other nodes can discover and retrieve these records using the `GET_PROVIDERS` query.
+
+```rust
+    // Start providing a record to the network.
+    // This stores the record in the local provider store and starts advertising it to the network.
+    kad_handle.start_providing(key.clone());
+
+    // Wait for some condition to stop providing...
+
+    // Stop providing a record to the network.
+    // The record is removed from the local provider store and stops advertising it to the network.
+    // Please note that the record will be removed from the network after the TTL expires.
+    kad_provider.stop_providing(key.clone());
+
+    // Retrieve providers for a record from the network.
+    // This returns a query ID that is later producing the result when polling the `Kademlia` instance.
+    let query_id = kad_provider.get_providers(key.clone());
+```
