[ARFC] Add PAXG to Aave v3 Main Instance on Ethereum

[LlamaRisk]

@ChaosLabs

As the PAXG token is tradable 24/7, it differs from the trading hours of the underlying gold. This often causes deviations from the gold oracle price, which is not updated during the weekend.
Our analysis has observed the biggest deviation to have occurred between the PAXG and XAU oracle prices to be of 22.2% in April 2024 during the Iran attack on Israel.

This datapoint is very insightful, and we agree with @ChaosLabs’ recommended Oracle (XAU).
