subcommands don't get description but get help anyway

[fdev31]

Thank you for the project, I like the idea to stick to a small Python app for it and re-use some well known APIs...

... but struggle generating some completion file.
I think there are some issues in shtab but it could also be a mis-usage.

• Using https://github.com/hyprland-community/pyprland/blob/main/scripts/pypr.py
• Running shtab -u --prog pypr --shell=zsh pypr.get_parser

1. it looks like add_help option to ArgumentParser only applies to the "root", I couldn't find a way to also avoid it in subparsers
2. the generated completion looks fine but misses the description for every subcommand
