New API to create Global Data Nodes

[FlorianJacta]

What would that feature address Creating Global Data Nodes and using them in a Taipy Core application will be simplified.

Description of the ideal solution tp.create_global_data_node(<Data Node Config>) should create the Data Node. The method should raise a dedicated error if the data node config is not global.

Documentation

• Add new entry in the release notes
