[ARFC] Reserve Factor Updates - Polygon Aave v2

Hi Everyone :wave:

After a successful Snapshot vote, we have now published the corresponding AIP.

In line with the original proposal, we will assess the affect of the current AIP and then follow up here with a comment detailing the next increase to the Reserve Factor (RF) before proceeding to AIP (ref. Step 3, Sect. Next Steps). At this point in time, we are planning on submit a 5% RF increase at the start of September.
