Missing transfer-spl from examples

[trentbrooks]

In the examples repo, there is a transfer-spl page view here: https://github.com/solana-developers/solana-actions/blob/main/examples/next-js/src/app/transfer-spl/page.tsx. But the code for the related api/actions/ is missing https://github.com/solana-developers/solana-actions/tree/main/examples/next-js/src/app/api/actions.

Thanks for flagging! I had planned to ship this example for actions and SPL transfers at launch, but did not get around to finishing it. So I siply removed the "transfer spl" card from the hope page
