### Summary
🌐🚀🔧

<!--
1. 🌐 - This emoji represents the addition of support for a new network
(Polygon ZK-EVM) to the PancakeSwap frontend, which is a global and
cross-chain platform for decentralized exchange and yield farming.
2. 🚀 - This emoji represents the improvement of the performance and
stability of the multicall requests on the Polygon ZK-EVM network, which
is a fast and scalable network that uses zero-knowledge proofs to verify
transactions.
3. 🔧 - This emoji represents the modification of the `batchSize`
property of the `multicall` option in the `viewClients` function, which
is a technical and configuration change that affects how the frontend
interacts with the multicall contract.
-->
Reduced `batchSize` for multicall requests on Polygon ZK-EVM network in
`viem.ts`. This improves performance and stability on the network with
lower gas limit.

> _`batchSize` shrinks_
> _for Polygon ZK-EVM_
> _autumn leaves fall fast_

### Walkthrough
* Reduce the multicall batch size to 128 on Polygon ZK-EVM network to
improve performance and stability
