[ARFC] Polygon v2 Borrow Rate Adjustments

After the snapshot successfully passed signalling this the right direction, valuable feedback was received on the proposed slope 2 rates. These parameters have been reviewed and brought down to 134%. We will present them as such in the upcoming AIP for the DAO to vote for.

Further to the above, the 12.75% Slope1 was revised to 9.75% which incorporates the intended 0.75% increase as proposed and also the revised v3 and v2 Slope1 parameter presented in this forum post.
