[I] [Python] Instantiating arrays with type List[ExtensionType] is not supported [arrow]

   ### Describe the bug, including details regarding any error messages, 
version, and platform.
   
   Instantiating an array with a `JsonType` works without a problem:
   
   ```
   import pyarrow
   
   json_type = pyarrow.json_()
   
   array = pyarrow.array(
       [
           "{'a': 1}"
       ],
       type=json_type,
   )
   ```
   
   Trying the same, but wrapping the JsonType inside a ListType doesn't work 
though:
   
   ```
   list_json_type = pyarrow.list_(json_type)
   list_array = pyarrow.array(
       [
           [
               "{'a': 1}"
           ]
       ],
       type=list_json_type,
   )
   ```
   
   =>
   
   ```
   Traceback (most recent call last):
     File "test.py", line 14, in <module>
       list_array = pyarrow.array(
     File "pyarrow/array.pxi", line 372, in pyarrow.lib.array
     File "pyarrow/array.pxi", line 42, in pyarrow.lib._sequence_to_array
     File "pyarrow/error.pxi", line 155, in 
pyarrow.lib.pyarrow_internal_check_status
     File "pyarrow/error.pxi", line 92, in pyarrow.lib.check_status
   pyarrow.lib.ArrowNotImplementedError: extension
   ```
   
   ```
   $ python -c "import pyarrow; print(pyarrow.__version__)"
   19.0.0
   ```
   
   It seems to be the same across all extension types, one can see similar 
behaviour for `FixedShapeTensor` type for example.
