[ARFC] Further increase GHO Borrow Rate

We support @monet-supply’s suggestion, as we mentioned something similar in our voting action rationale on the last GHO Borrow Rate increase. It’s important to provide predictability on how GHO’s parameters are handled to foster trust among all market participants.

In our opinion, an algorithmic implementation like the one suggested seems to be the right approach to achieve the above, also allowing for the ability to swiftly handle a hypothetical overpeg scenario.
