Infer array current item schema (#15115)

This PR allows to infer the schema of the current item of an iterator
step:
- iterator step receive a variable
- added an util that navigate to the array in schema -
navigateOutputSchemaProperty
- use the array value in schema to generate a new schema - used the
existing getFunctionOutputSchema that I renamed and moved to
twenty-shared

Also cleaned a bit the existing schema for AI.
