📜🔺 contract upgrade

Context

This proposal is a ptach for the 3.2 upgrade which was executed in AIP 178. The patch upgrades the pool contract across all markets, to add an extra fallback on the getReserveData() view function, allowing for integrators unable to update peripheral contracts (Aave Pool Data Provider) to still be compatible with v3.2.

Technical analysis

We have verified that the proposal upgrades all the pools on all the v3 markets to match the latest patch which includes an extra fallback on the getReserveData() view function which will be a dummy stable debt token (one that existed before the 3.2 patch), which will always return 0 on total supply and other filed such as balanceOf, in order to return real data and prevent reverts of the function.

The proposal is consistent with the description on both Snapshot and the governance forum.
