[DMN Designer] The Input Node type should be synchronised with the column type in the Decision Table

When the user persists the following diagram:

..with the following Decision Table:

..and change the Input Node type, the type in the Decision Table does not change.

Steps to reproduce

Expected behaviour
Ideally, those types should be synchronised. However, since the type in the DT column is persisted as dmn:inputExpression and the type in the Input Node is persisted as a dmn:variable, the user should be able to re-define the types, keeping them unsynchronised.
