* feat(devkit): split create-empty-tree to different functions
* chore(repo): apply migration for createEmptyTree
* cleanup(misc): fix tests that migration misses
1- Implement a hook generator which provides the skeleton for a new hook, including a test which
uses @testing-library/react-hooks
2- add --pascalCaseDirs to the component generator, so you can
have 'SomeComponent/SomeComponent.tsx' instead of 'some-component/SomeComponent.tsx'
