docs: clarify that V5Bootnodes should reference Execution Layer nodes only

Browse source 
The previous comment in bootnodes.go implied that the hardcoded discv5 bootnodes
were Consensus Layer (CL) nodes. This caused confusion since Geth is an Execution
Layer (EL) client and should not reference CL bootnodes (e.g., Teku, Prysm,
Lighthouse, Nimbus).

This change updates the documentation comment above V5Bootnodes to clearly state:
- These bootnodes are used for Execution Layer peer discovery only.
- Consensus Layer bootnodes should not be hardcoded here.
- The list should only contain EL bootnodes in enr:// or enode:// format.

This improves clarity for developers and contributors reviewing or updating
the node discovery configuration in the future.
