Add ui_customizations "redesigned_confirmation" metric for transactions

[digiwand]

What is this about?

Currently, we add the ui_customizations "redesigned_confirmation" event property for redesigned signatures. This happens in createRPCMethodTrackingMiddleware.js. We will need to add the same property for redesigned transactions.

A challenge with doing this in createRPCMethodTrackingMiddleware.js is that the method we check is the eth method. For the contract interaction transaction type, the method would equal eth_call. We can consider using updateTransactionEventFragment for the solution.

Repro:

1. set ENABLE_CONFIRMATION_REDESIGN=true in .metamaskrc
2. enable Experimental > Redesign Confirmation in settings
3. enable Participate in MetaMetrics in settings
4. test redesigned transactions (Contract Interaction) e.g. test-dapp Mint NFT
5. observe "Transaction <Rejected|Canceled|Approved>" event with new ui_customizations
