Update all component data source documentation to reflect the removal of CKComponentDataSource

[eczarny]

CKComponentDataSource and CKCollectionViewDataSource have been replaced with CKTransactionalComponentDataSource and CKCollectionViewTransactionalDataSource, respectively. The collection views ComponentKit documentation needs to be updated, including any diagrams, to reflect this change.

Most important is providing an up-to-date example of how to use component with UITableView based on the new CKTransactionalComponentDataSource API.
