Update price feeds in cWstETHv3 on Mainnet with CAPO implementation.

Proposal summary

This proposal updates existing price feeds for rsETH and ezETH on the wstETH market on Mainnet.

CAPO summary

CAPO is a price oracle adapter designed to support assets that grow gradually relative to a base asset - such as liquid staking tokens that accumulate yield over time. It provides a mechanism to track this expected growth while protecting downstream protocol from sudden or manipulated price spikes. rsETH and ezETH price feeds are updated to their CAPO implementations.

Further detailed information can be found on the corresponding proposal pull request and forum discussion for CAPO.

CAPO audit

CAPO has been audited by OpenZeppelin, as well as the LST / LRT implementation here.
