compatibility issue within the 'execute' method of a Command in Symfony Console version 7

[GigaCode93]

Bug Report

Current Behavior
In Symfony 7, the execute method of Symfony Command now requires a return value of type int as part of its method signature. However, this requirement has not been implemented in your extension's Commands. Additionally, your code includes the strict types declaration declare(strict_types=1);. As a result, it leads to a fatal error due to this incompatibility.

Expected behavior/output
Preventing fatal errors and ensuring compatibility.

Environment

• TYPO3 version(s): 12.4.10
• tt_address version: 8.0.2
• Is your TYPO3 installation set up with Composer (Composer Mode): yes
• OS: Ubuntu 22

Possible Solution
Modifying the method signature to make it compatible with the execute method of the Symfony command, or alternatively, removing declare(strict_types=1);.
