Polygon Testnet setup lacks Chain ID

[cfravel]

This page: https://docs.decentraland.org/development-guide/second-layer/ at the bottom, provides info about how to hook MetaMask up to Polygon test net. However the info isn't quite complete, it lacks the Chain ID

Although it links to the Polygon docs where the full information is, providing part of the info but not all of it seems less than ideal.

Here is the full info from the Polygon site:
