Unhandled exception with multiple --quiet flags

[yggdr]

Describe the bug
Giving -q more than twice to commands like list gives unhandled exception:

$ pipx list -qqq
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/logging/config.py", line 564, in configure
    handler = self.configure_handler(handlers[name])
  File "/usr/local/lib/python3.9/logging/config.py", line 758, in configure_handler
    result.setLevel(logging._checkLevel(level))
  File "/usr/local/lib/python3.9/logging/__init__.py", line 198, in _checkLevel
    raise ValueError("Unknown level: %r" % level)
ValueError: Unknown level: 'Level 60'

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/usr/local/bin/pipx", line 8, in <module>
    sys.exit(cli())
  File "/usr/local/lib/python3.9/site-packages/pipx/main.py", line 916, in cli
    setup(parsed_pipx_args)
  File "/usr/local/lib/python3.9/site-packages/pipx/main.py", line 856, in setup
    setup_logging(verbose)
  File "/usr/local/lib/python3.9/site-packages/pipx/main.py", line 846, in setup_logging
    logging.config.dictConfig(logging_config)
  File "/usr/local/lib/python3.9/logging/config.py", line 809, in dictConfig
    dictConfigClass(config).configure()
  File "/usr/local/lib/python3.9/logging/config.py", line 571, in configure
    raise ValueError('Unable to configure handler '
ValueError: Unable to configure handler 'stream'

How to reproduce

pipx list -qq works fine, pipx list -qqq does not.

Expected behavior

Either ignore the superfluous q-flags, or print a notice about the number of times this subcommand accepts the flag.
