Write a thorough FAQ area to explain what to do in case of DKG troubles

🎯 Problem to be solved

An issue with clusters during the DKG process could appear multifaceted, involving both software and human error components. There should be clear guidelines to explain what to do in case of issues.

🛠️ Proposed solution

Write a FAQ page for accurate diagnosis, such as:

• Running DKG in debug mode (--log-level=debug --log-color=disable)
• Sharing and analyzing full logs rather than screenshots or partial logs
• Ensuring the .charon directory is clean and only contains charon-enr-private-key
• checking the existence of a validator_client directory from a previous DKG attempt, which could cause issues.
• checking any errors related to relay circuits (NO_RESERVATION (204)) and peer connection failures (sync client: read size: EOF) which suggest potential issues with relay handling and peer connections
• Updating and monitoring relays as part of the ongoing management.
• making sure of the synchronous running of the DKG ceremony and ensuring all nodes complete the process without premature exits
