[docs] [issue23487] argparse: add_subparsers 'action' broken

[paul j3]

paul j3 added the comment:

I'm going to close this.  At most it calls for a documentation change.  But saying something like

   It must be compatible with argparse._SubParsersAction.

will just confuse the average user.  Any customization of this action class is an advanced topic, that requires familiarity with the code, not just the documentation.
