Fungible faucet dapp using deprecated method getFeePurse

[ktomascz]

Describe the bug

When trying to deploy dapp-fungible-faucet to devnet it fails with RemoteTypeError(error:captp:unknown#20001)#1: target has no method "getFeePurse", has ["tapFaucet"]
This is very like due to using deprecated methods in the contract deploy script.
Please, see: https://github.com/Agoric/dapp-fungible-faucet/blob/main/contract/deploy.js#L67

To Reproduce

1. Start devnet chain (agoric start --reset testnet 8000 https://devnet.agoric.net/network-config)
2. Try to deploy the fungible faucet dapp.

Expected behavior

Dapp deploys with success.

Platform Environment
