tox --help reports wrong default verbosity

Issue

tox --help says

verbosity:
  every -v increases, every -q decreases verbosity level, default INFO, map 0=CRITICAL|1=ERROR|2=WARNING|3=INFO|4=DEBUG|5=NOTSET

  -v, --verbose               increase verbosity (default: 2)
  -q, --quiet                 decrease verbosity (default: 0)

which is confusing, because it claims the default verbosity to be both 3/INFO and 2/WARNING. Experiments show that 2/WARNING is the true default verbosity.

I'll submit a PR to fix this shortly, but I need an issue number for the changelog note.

Environment

• OS: Ubuntu 22.04
• tox 4.0.11 (actually the current git main snapshot)
