Why do I need G tokens on Ethereum mainnet when I bridge other assets to Gravity Alpha Mainnet?

Bridging assets from the Ethereum mainnet to Gravity Alpha Mainnet involves two transactions. The first transaction is initiated on the Ethereum mainnet, and the second is a system transaction on the Gravity Alpha Mainnet that distributes funds to the recipient. Since Gravity Alpha Mainnet is an Arbitrum Nitro rollup, the cost of the system transaction on the Gravity Alpha Mainnet must be covered by the initiating transaction on the Ethereum mainnet. Additionally, since the Gravity Alpha Mainnet uses G tokens, the initial deposit transaction also requires some G tokens.
