Add react app transaction sample

I'm glad you're finding the library useful! Looking at your project, it seems like some of the functionality we want to highlight is already demonstrated in the Usage sample code in the readme: https://github.com/solana-labs/wallet-adapter#usage

The example code also has some of this kind of functionality: https://github.com/solana-labs/wallet-adapter/blob/e6bcd3c36929709a604637260de556275573c726/packages/example/src/SendTransaction.tsx#L20-L31

These use the sendTransaction interface here: https://github.com/solana-labs/wallet-adapter/blob/e6bcd3c36929709a604637260de556275573c726/packages/base/src/signer.ts#L13-L40

Is there something you think it would be valuable to add to these? I think where this library can use the most help is in documenting the features it has.

Oh actually I did not notice about SendTransaction.tsx implementation was there! So BaseSignerWalletAdapter covers the transaction implementation which I implemented in my project. Cool!

Yeah perhaps adding some documents for useWallet hooks might be helpful for devs. I'll try to see if I can contribute to anything in the project. Meanwhile let me close this issue, thanks for your input!
