genesis: Skip inserting genesis accounts for Development clusters (#35266) 

solana-genesis currently includes a list of accounts that exist in
MainnetBeta genesis. These accounts are added for all cluster types,
including Development clusters.

There is no need for these accounts to get added to dev clusters so
skip adding them for ClusterType::Development case
