Replace deprecated Symfony Console add() with addCommand()

[ozdemirburak]

This PR fixes the warning below:

Since symfony/console 7.4: The "Symfony\Component\Console\Application::add()" method is deprecated and will be removed in Symfony 8.0, use "Symfony\Component\Console\Application::addCommand()" instead.

Wouldn't you need to bump the symfony/console to ^7.4 to ensure the new command is present? I think that's why the "lowest" tests are failing.

"symfony/console": "^7.4" requires PHP >= 8.2
"tightenco/jigsaw": "1.8.3" requires PHP ^8.2

So it should be possible to "just" bump the requirements

Hi, sorry, I didn't see this PR before starting work on mine (#768).
I've already addressed the issue, and all tests passed.

The problem with this PR is as @tomasnorre mentioned.
However, the minimum version is actually 7.1. From the Composer log, we see that the failing tests installed 7.0.

Thanks, just updated composer.json. Though, according to this CHANGELOG, it is 7.4 where addCommand was introduced.

[midnight-wonderer]

In my PR, I used addCommands, which has been available since 7.1:
https://github.com/symfony/console/blob/7.1/Application.php#L502
This, IMO, not only supports a wider range of versions but is also more idiomatic for the use case in Jigsaw.

I guess, I'll leave mine open, just in case.
