Test the Transparent Proxy pattern for upgrading smart contracts.

1. Deploy a Box implementation contract
2. Deploy a ProxyAdmin contract to be the admin of the proxy
3. Deploy a TransparentUpgradeableProxy to be the proxy for the implementations

Then, the upgrade script will:

4. Deploy a new Box implementation BoxV2
5. Upgrade the proxy to point to the new implementation contract, essentially upgrading your infrastructure.
6. Then it will call a function only BoxV2 can call
