Update All Cross VM Tutorials & Repos to use `@onflow/react-sdk`

[jribbink]

We have released the Flow React SDK with native support for aspects of the cross-VM tutorial that were originally written manually (running a Cadence batch transaction).

This should be updated to use useCrossVmBatchTransaction from @onflow/react-sdk instead of the custom batch transaction hook used in the tutorial/repo.
