Description

I propose that the prefer-optional-chain should suggest combining logical expressions that start with an optional chain

Discovered while making test cases in #5594

Yeah the only issue I've found is that it really is suuuper complicated to write all the logic to make this work.

It looks so easy on paper, but comparing two asts and understanding how they relate in the general case to determine the appropriate fix is just really difficult to do.
