[Bug] Arch/Manjaro: 'MILC' object has no attribute '_subcommand'

[nstetter]

Describe the Bug

When trying to compile any firmware QMK fails with the error:

~/qmk_firmware❯ qmk compile -kb keebio/iris/rev3 -km default

<class 'AttributeError'>
☒ 'MILC' object has no attribute '_subcommand'
Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/milc/milc.py", line 467, in __call__
    return self.__call__()

    return self._entrypoint(self)
  File "/home/norman/qmk_firmware/lib/python/qmk/decorators.py", line 20, in wrapper
    if cli.config_source[cli._subcommand.__name__]['keyboard'] != 'argument':
AttributeError: 'MILC' object has no attribute '_subcommand'

The same when directly invoking make:

~/qmk_firmware ❯ make keebio/iris/rev3:default  
QMK Firmware 0.13.2
Making keebio/iris/rev3 with keymap default

Additional Context

Same here, pip install milc --upgrade should get you milc >= 1.4 which has cli._subcommand.

Requirements.txt might need to be updated to reflect that.

Edit: I think this is related to #13046

@pierre-vo, thanks for the hint. Upgrading milc resolves the issue.
