fix: add xcmVersion arg to DryRunCall

[Imod7]

Closes: #547

Description

The Kusama runtime was upgraded to version 1005000 and the DryRunCall now takes also the xcmVersion as an argument. Polkadot is still in version 1004001 so it still takes 2 arguments. The change in this PR makes asset-transfer-api work for both upgraded and non-upgraded runtimes.

Testing

You can test the change by running the below demo for Kusama by adding the xcmVersion in the arguments:

const { AssetTransferApi, constructApiPromise } = require('../asset-transfer-api'); // the locally linked package

const main = async () => {
    const { api, specName, safeXcmVersion } = await constructApiPromise('wss://kusama-rpc-tn.dwellir.com');
    const assetTransferApi = new AssetTransferApi(api, specName, safeXcmVersion);
    const sendersAddr = '16FNntR3F4ZjsTdYHysWSiP2vGHoVL7uZ9tyfyd4o5Cdaghf';
    const tx = '0x040000886d225c2e5ea37cf074eedbeb62d7e1e737e36e8e0b74d6e302cac82269ab491300408b43d2ee2e06';
    
    const dryRunResult = await assetTransferApi.dryRunCall(sendersAddr, tx, 'call', safeXcmVersion);
    console.log('dryRunResult', JSON.stringify(dryRunResult));
}
main();

and this demo for Polkadot without giving the xcmVersion as an argument

import { AssetTransferApi, constructApiPromise } from 'asset-transfer-api'; // the locally linked package

const main = async () => {
    const { api, specName, safeXcmVersion } = await constructApiPromise('wss://rpc-polkadot.luckyfriday.io');
    const assetTransferApi = new AssetTransferApi(api, specName, safeXcmVersion);
    const sendersAddr = '16FNntR3F4ZjsTdYHysWSiP2vGHoVL7uZ9tyfyd4o5Cdaghf';
    const tx = '0x07000f0040396b3a350100';
    
    const dryRunResult = await assetTransferApi.dryRunCall(sendersAddr, tx, 'call');
    console.log('dryRunResult', JSON.stringify(dryRunResult));
}
main();

Please link the above demos to the asset-transfer-api package that you have cloned locally and checked out in the current branch (which contains the fix).
