Add expected lodestar warning in FAQs

[dB2510]

🎯 Problem to be solved

With v0.16.0 release we made lodestar our default VC in charon-distributed-validator-node repo. Lodestar logs some warnings in console which are expected. We need to add these logs to our FAQs section of Errors & Resolutions.

🛠️ Proposed solution

Add lodestar warning logs to Errors & Resolutions. Lodestar logs following warnings:

Jul-12 12:44:36.261[]                 warn: Potential next epoch attester duties reorg slot=6861821, dutyEpoch=214432, priorDependentRoot=0xa08b0d0000000000000000000000000000000000000000000000000000000000, newDependentRoot=0xc68535c177b97d0f5ca2c2c50888563b6d63fe5c91ede07b86e96df93d64368f

Lodestar logs these warnings because charon is not able to return proper dependent_root value in getAttesterDuties API response whenever lodestar calls this API. This is because charon uses go-eth2-client for all the beacon API calls and it doesn't provide dependent_root value in responses. We have reported this to them here.
