Low`_getUnderlyingAmount()` Design IntentFixed

The function `_getUnderlyingAmount()` calls `LSTPerToken()` on the zkETH contract, which does the following ```solidity function LSTPerToken() external view returns (uint256) { return _getWrappedLiquidStakedTokenStorage().lst.convertToAssets( 1 ether, true ); } ``` Similarly to the wstETH oracle, this could instead call `convertToAssets(1 ether,true);` directly on the rzkETH contract to save gas. However, the zkETH contract is upgradeable while the wstETH contract is not, so that it is possible that the `LSTPerToken()` function's behavior is changed in the future, which is not the case for wstETH.
