feat(blocks): Add CreateDictionaryBlock and CreateListBlock (#8903)

Though this is technically possible with the AddToDictionary and
AddToList Blocks, that approach alone feels like a hidden work-around
rather than an intuitive feature, and I'm happy with the duplication in
the name of better experience for our users here.

Changes 🏗️
Added CreateDictionaryBlock class that creates a dictionary from the
provided key-value pairs.
Added CreateListBlock class that creates a list from the provided
values.
