Add TransferableReceivable on Sepolia

[MantisClone]

Problem(s)

1. We cannot detect TransferableReceivable payments on Sepolia. The TransferableReceivable contract was deployed on Sepolia in Deploy ERC20TransferableReceivable on Sepolia requestNetwork#1416, but was never added to the payments-subgraph.

2. The Invoicing Template Dashboard displays "unsupported network" error when querying the balance of TransferableReceivable requests.

Proposed Solution

To detect payments, we must add the TransferableReceivable to the payment-subgraph on Sepolia.
