streamline reviews

[sakulstra]

@kartojal noted that sometimes reviews here are a bit slow.

The bottleneck currently is that we always manually check:

• that each contract is verified on the most popular explorer of that chain
• that the contracts are in fact the correct contracts
• in some rare cases we even diff the contracts (or ask the pr creator to provide a diff)
• for some we manually check that they are correctly configured

I think at least the first 3 points should be perfectly automatable. No good idea yet how, but is possible for sure.

1) is now done in https://github.com/bgd-labs/aave-address-book/pull/570 - visuals can be improved etc, but we now have a ci action reporting if added addresses are verified or not (on mainnets only atm)
