Michael Layzell 94946f20ce Update usage of syn in Procedural Macros chapter ...

This makes 2 changes:
1. It updates the versions of `syn` and `quote` to the latest versions.
2. It updates the code to not use the deprecated type alias `syn::MacroInput` and instead use the preferred `syn::DeriveInput`. `MacroInput` will be removed in the next breaking version of `syn`. See https://github.com/dtolnay/syn/pull/173
