No output from pipx upgrade-all when no packages have upgrades

[ezio-melotti]

Describe the bug

Before (in 1.4.x?), pipx upgrade-all used to print a message that said No packages upgraded after running 'pipx upgrade-all'. After upgrading to 1.6.0 the message is gone, and upgrade-all produces no output (there is some output while it tries to upgrade the installed packages, but no output remains after the command is executed).

I'm not sure if this was an intentional change or a bug. The code was recently changed in c9d31a6 (#1357 by @huxuan) and the message is still there:

pipx/src/pipx/commands/upgrade.py

Lines 264 to 265 in 99c998d

	if len(upgraded) == 0:
	print(f"No packages upgraded after running 'pipx upgrade-all' {sleep}")

however I don't see it in the output, even while using -v (I see several other lines of output though).

How to reproduce

Make sure that all packages are upgraded, then run pipx upgrade-all.

Expected behavior

I would like to see a message stating that currently no package needs upgrades.

Note that I noticed the issue after updating Ubuntu from 24.04 to 24.10.
pipx is installed through apt, and 24.04 had pipx 1.4.x.
