`ast.NameCostant` Deprecation in Python 3.14

Starting with py3.13 we're getting the following warning emitted:

DeprecationWarning: ast.NameConstant is deprecated and will be removed in Python 3.14; use ast.Constant instead

Which is used here:

Lines 403 to 409 in 50ad178

    
           if node.value is not None: 
        
               # In the event of an explicit `None` return (`return None`), the node body will be an 
        
               # instance of either `ast.Constant` (3.8+) or `ast.NameConstant`, which we need to check 
        
               # to see if it's actually `None` 
        
               if isinstance(node.value, (ast.Constant, ast.NameConstant)):  # pragma: no branch 
        
                   if node.value.value is None: 
        
                       return

Judging from the note from past me I think this can already be dropped since py3.7 support has been removed.
