Updated walkthrough code examples to match the solution repo in interact-with-wallets

[bqmackay]

In the lab section of the Interact with Wallets page, the WalletContextProvider code uses the useMemo function to get wallets, but the solution code correctly uses walletAdapterWallets.

Here's the broken code from the lab:

#...imports...

const Home: NextPage = (props) => {
  const endpoint = web3.clusterApiUrl("devnet");
  const wallets = useMemo(() => [], []); # <===== useMemo is here, but not imported from React

And here's the correct line from the solution repo:

const wallets = [new walletAdapterWallets.PhantomWalletAdapter()];

Thanks @bqmackay - the courses have now been migrated to https://solana.com/developers/courses and https://github.com/solana-foundation/developer-content/tree/main/content/courses - can you please send a PR to that repo?
