[no issue] fix host type

https://github.com/curvegrid/hardhat-multibaas-plugin/blob/main/src/deploy.ts#L62

const requestURL = new URL(path, this.mbConfig.host);

In order to not URL a URL, we should make the mbConfig host a string. Or alternatively, we could have modified the line above to do this.mbConfig.host.toString() before making it a URL again.

If we keep the type as a URL, then it is an extra import required in the hardhat config, so personally I think we should just make it a string.

The problem only happens when using node v20 nodejs/node#50891
But the cause of the issue may not be node itself hapijs/wreck#305

Basically in src/deploy.ts, in request, accessing this.mbConfig is fine, but accessing this.mbConfig.host causes an error
