title: Enable async backing on all testnet system chains

doc:
  - audience: Runtime User
    description: |
      Async backing has been enabled on all testnet system chains: asset-hub-westend,
      bridge-hub-westend, bridge-hub-rococo, collectives-westend, contracts-rococo,
      coretime-westend, coretime-rococo, people-westend, and people-rococo. These now target 6s
      block times.
      For the running coretime chains, that requires updating the configuration after the runtime
      upgrade but before the end of the current region.
