Summary of changes

Set the default logging level to WARNING, so debug log messages won't be shown without passing additional flags such as --verbose.

Closes #1175
Closes #1177

Test plan

Tested by running

nox -s tests-3.12

Probably we need to update this line to ERROR and CRITICAL logging levels.?

pipx/src/pipx/main.py

Line 720 in 81c2fa5

" WARNING, ERROR, and CRITICAL logging levels."

[chrysle]

Yes, looks like it.

The "-q" added in #1159 shall also be removed:

pipx/tests/test_list.py

Line 83 in 81c2fa5

assert not run_pipx_cli(["list", "-q", "--json"])

We can change its behavior instead of removing it. I remember the original usage of this flag was hiding all console outputs, not just the debug log messages.

It might be so but:
IMHO, it should have raised a red flag in review (but can be easily missed).
Removing the flag in that test allows to see that the default log level is the correct one (for now, it seems it's the only test for that - although probably accidental).
Given this PR reverts the default log level to WARNING, I think we should also revert this change that was only introduced because of the default log level change.

If there are more changes to be made as you suggest, then it would be for another PR but for now, I think changing back this test is the best option.

I've opened #1181 to revert it now.
