[L-4] Yield update will not happen at the 1k ETH threshold
Yield updates happen for a vault when the `BRIDGE_YIELD_UPDATE_THRESHOLD` is met for the vault after a large bridge deposit. The `maybeUpdateYield` function handles this logic for updates when that happens (1000 ETH to be exact).\\nThreshold constant from:\\n```\\nFILE: 2023-09-ditto/contracts/libraries/Constants.sol\\n\\nLine 17:\\nuint256 internal constant BRIDGE_YIELD_UPDATE_THRESHOLD = 1000 ether;\\n\\nLine 18:\\nuint256 internal constant BRIDGE_YIELD_PERCENT_THRESHOLD = 0.01 ether; // 1%\\n```\\n\\n```\\nFILE: 2023-09-ditto/contracts/facets/BridgeRouterFacet.sol\\n\\nfunction maybeUpdateYield(uint256 vault, uint88 amount) private {\\n        uint88 zethTotal = s.vault[vault].zethTotal;\\n        if (\\n            zethTotal > Constants.BRIDGE_YIELD_UPDATE_THRESHOLD\\n                && amount.div(zethTotal) > Constants.BRIDGE_YIELD_PERCENT_THRESHOLD\\n        ) { // @audit should be >= to account for when threshold is met\\n            // Update yield for "large" bridge deposits\\n            vault.updateYield();\\n        }\\n    }\\n```\\n
Change the `>` operand in the `maybeUpdateYield` function to be `>=`.
In reality the yield update for the vault will not happen in the instances of 1000 ETH deposits unless the bridge deposit amount into the vault is > 1000 ETH and the percent is greater than 1%.
