* Add tsconfig to components directory and include it as project
* Add @types/classnames package
* Migrate Label component to TSX
* Remove unused imports from Label component
* fix package-lock.json
It was generated with npm 7 and we don’t support that yet (and that update should be done in a separate pull)
* Add interface for LabelProps and implement.
Also:
- import `Fragment` from @wordpress/element.
- import `HTMLAttributes` explicitly as a type from react (@types/wordpress__element doesn’t export this interface).
* fix jest configuration
