Description

This proposal aims to increase the backing timeout on validators from 2s to 2.5s and approval-voting timeout from 12s to 15s respectively.

The rationale for the change can be found in https://github.com/paritytech/polkadot-sdk/issues/3565. In short, this will help ensuring smoother experience for async backing parachains wishing to utilize the full 2s of execution per block.

Checking

The details of the call can be found here: https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Frpc-kusama.luckyfriday.io#/extrinsics/decode/0x332e0c01002000000600c4090000000000000601983a000000000000.

In addition to setting the timeouts, the MaxMemoryPage param is being set to the value it was set before, since the call overrides every param of ExecutorParams.

Testing

This call has been tested locally with zombienet as well as on Rococo.
