summary:

argparse: Remove unused name variable when handling ArgumentTypeError (#96549)

This removes the unused `name` variable in the block where `ArgumentTypeError` is handled.

`ArgumentTypeError` errors are handled by showing just the string of the exception; unlike `ValueError`, the name (`__name__`) of the function is not included in the error message.

Fixes #96548
