replace fund-link with transfer-link

[mscurtescu]

A fund-link task is referenced:

npx hardhat fund-link --contract insert-contract-address-here --network network

but there is no such task. Most likely this should be replaced with the transfer-link task and run something like:

npx hardhat transfer-link --recipient insert-contract-address-here --linkaddress insert-link-address-here --amount 1000000000000000000 --network network

The deploy script shows how to run the transfer-link task and provides the LINK address.
