ProxyClassRebuildCommand is not symfony/* 7.0 compatible

Bug Report

Current Behavior
I got following error:

Fatal error: Declaration of GeorgRinger\News\Command\ProxyClassRebuildCommand::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output) must be compatible with Symfony\Component\Console\Command\Command::execute(Symfony\Component\Console\Input\InputInterface $input, Symfony\Component\Console\Output\OutputInterface $output): int in /var/www/html/vendor/georgringer/news/Classes/Command/ProxyClassRebuildCommand.php on line 26

Expected behavior/output
No error message

Environment

• TYPO3 version(s): [12.4.10]
• news version: [e.g. 11.3.0]
• Is your TYPO3 installation set up with Composer (Composer Mode): [yes]

Possible Solution

• Do not support symfony/* packages 7.0
• Make execute compatible to new symfony version

In general, I'd recommend using explicit dependencies (e.g., on symfony/console) in the composer.json when the extension relies on components/packages instead of depending on transitive dependencies (which caused this problem).

In general, I'd recommend using explicit dependencies (e.g., on symfony/console) [...].

This, and tools like Rector would've identified this beforehand. The offending change is known since Symfony 5.x (no offense, tho).
