[Bug]: 3rdparty incompatible dependencies: stecman/symfony-console-completion and symfony/console

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.

Bug description

PHP Fatal error: Declaration of Stecman\Component\Symfony\Console\BashCompletion\CompletionCommand::mergeApplicationDefinition($mergeArgs = true) must be compatible with Symfony\Component\Console\Command\Command::mergeApplicationDefinition(bool $mergeArgs = true): void in /var/www/nextcloud/3rdparty/stecman/symfony-console-completion/src/CompletionCommand.php on line 57

Steps to reproduce

After upgrading to version 6.1.1 and updating Next cloud to 28.0.3, I receive a message in the admin panel about the need to download models (they were downloaded earlier and everything worked fine). When trying to run in /var/www/next cloud "sudo -u www-data php c recognize:download-models" I get the following message "PHP Fatal error: Declaration of Stecman\Component\Symfony\Console\BashCompletion\CompletionCommand::mergeApplicationDefinition($mergeArgs = true) must be compatible with Symfony\Component\Console\Command\Command::mergeApplicationDefinition(bool $mergeArgs = true): void in /var/www/nextcloud/3rdparty/stecman/symfony-console-completion/src/CompletionCommand.php on line 57"

Additional info

original issue: https://github.com/nextcloud/recognize/issues/1107

Start with 3rdparty/stecman/symfony-console-completion/src/CompletionCommand.php at line 57 and compare the reported declaration with Symfony\Component\Symfony\Console\Command\Command. Reproduce the failure by running sudo -u www-data php c recognize:download-models, and review the linked recognize issue for context. Done means the command executes without the fatal compatibility error.
