Updates to chapter 2.2 - Githubissues

A few thoughts on chapter 2.2:

[ ] exercise 2.2.2 should have more prints(). In general, we should add as many prints as we can to the exercises so they're more interactive and give more feedback to the users. @bitschmidty
[ ] exercises 2.2.3 and 2.2.4 should unseal the commitment (ie the signer proves that they've committed to x) so it's obvious why being able to change the commitment is bad. This ties into https://github.com/bitcoinops/taproot-workshop/issues/86. Perhaps the commitment should be something like "Pay 0.1 BTC to Optech" and the fake commitment changes that to "Pay 10BTC to Optech". @jachiang
