Refactor registerTenantFinder method to reduce complexity

[misaf]

Hello,

I've refactored the registerTenantFinder method to improve readability and reduce complexity.

Changes Made:
Extracted the configuration lookup into a variable $tenantFinderConfig.
Improved code readability and maintainability by reducing repeated calls to config.

Benefits:
Reduced Complexity: By storing the configuration value in a variable, we avoid making multiple calls to the config method, making the code cleaner and more efficient.
Improved Readability: The refactored method is easier to read and understand at a glance.
I believe these changes will help maintain the codebase more effectively and look forward to your feedback.

Best regards,
Ehsan Mahmoodi
