Vulnerability: If the dao removes a bridge, user's deposited tokens for that bridge will be lost.
Severity: low

Description:
If the dao removes a bridge for any (non-malicious) reason, user's deposited tokens for that bridge will be lost.\\nIn the `OwnerFacet.sol` the dao of the system has the option to remove a bridge by calling the `deleteBridge()` function. There is no check if there are any assets in the bridge. Also users may deposit funds in the bridge during the voting period.\\nPOC Add the following function in the `BridgeRouter.t.sol`\\n```\\nfunction test_DeleteBridgeWithAssets() public {\\n        console.log("Sender ethEscrowed in vault 2 before deposit: ", diamond.getVaultUserStruct(2, sender).ethEscrowed);\\n        deal(_rethA, sender, 10000 ether);\\n\\n        vm.startPrank(sender);\\n        uint88 deposit1 = 1000 ether;\\n        uint88 withdrawAmount = 100 ether;\\n        diamond.deposit(_bridgeRethToBeDeleted, deposit1);\\n        console.log("Sender ethEscrowed in vault2 after deposit: ", diamond.getVaultUserStruct(2, sender).ethEscrowed);\\n        diamond.withdraw(_bridgeRethToBeDeleted, withdrawAmount);\\n        console.log("Sender ethEscrowed after withdraw: ", diamond.getVaultUserStruct(2, sender).ethEscrowed);\\n        vm.stopPrank();\\n\\n        console.log("Balance of reth in the bridgeRethToBeDeleted: ", rethA.balanceOf(_bridgeRethToBeDeleted));\\n\\n        /// INFO: DAO deletes the bridge after a vote has been passed\\n        vm.startPrank(owner) ;\\n        diamond.deleteBridge(_bridgeRethToBeDeleted);\\n        vm.stopPrank();\\n\\n        vm.startPrank(sender);\\n        vm.expectRevert();\\n        diamond.withdraw(_bridgeRethToBeDeleted, withdrawAmount);\\n        console.log("Balance of reth in the bridgeRethToBeDeleted: ", rethA.balanceOf(_bridgeRethToBeDeleted));\\n        vm.stopPrank();\\n    }\\n```\\n\\nIn order to run this test, you also have to add\\n```\\n rethA.approve(\\n                _bridgeRethToBeDeleted,\\n                0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff\\n            );\\n```\\n\\nto `setUp()` function of the `BridgeROuter.t.sol` contract\\nIn `DeployHelper.sol` another bridge and vault have to be added in order for the test to run:\\n```\\n/// INFO: added by auditor\\n    IBridge public bridgeRethToBeDeleted;\\n    address public

_setETH(4000 ether);\\n            }\\n```\\n\\nTo run the test use `forge test -vvv --mt test_DeleteBridgeWithAsset`

Impact:
User's deposited `RETH` or `STETH` in that bridge will be lost, as the user doesn't have the option to withdraw them. Because the withdraw functions can only be called trough the `Diamond.sol`

Recommended mitigation:
In `deleteBridge()` make sure that the contract doesn't have any assets
