* docs(toh-6/dart): refactoring of 'add, edit, delete heroes' Refactoring of "add, edit, delete heroes" section of toh-6 from one big bottom-up step into small independent feature slices, where the user achieves a "milesone" (i.e., can run the full app) after each feature section. The section rewrite is shorter and offers a better UX. Other simplifications: - Error handling is consistent: in the hero service we log to the console, everwhere else we just let errors bubble up. - Hero service methods renamed based on function (create, update) rather then lower-level implementation (post, put). - @Output properties have been eliminated (since they weren't explained). E2E tests now pass on both the TS and Dart sides. * docs(toh-6/ts): refactoring of 'add, edit, delete heroes' Refactoring of "add, edit, delete heroes" section of toh-6 from one big bottom-up step into small independent feature slices, where the user achieves a "milesone" (i.e., can run the full app) after each feature section.
