Argparse API change breaks argcomplete

[Matthias Lüscher]

Description: Ubuntu Noble Numbat (development branch)
Release: 24.04
python3-argcomplete: 3.1.4-1

Python argparse introduced an API change that breaks argcomplete. The upstream version of argcomplete got fixed here: https://github.com/kislyuk/argcomplete/commit/54a4846b3a774cd9037167898f3cce38ba9d58e8

I detected the issue using my python based tool edi. The issue can be reproduced as follows:

1. Install edi according to https://docs.get-edi.io/en/latest/getting_started.html#installing-edi-from-the-package-repository
2. Start to type "edi -v project" and hit tab for auto completion. The first level sub command will be proposed instead of the second level subcommand.
3. Patch /usr/lib/python3/dist-packages/argcomplete/packages/_argparse.py according to the above commit.
4. Start to type "edi -v project" and hit tab for auto completion. The correct second level commands such as "make" will be proposed.
