Configuration checks fixes

[devanshjainms]

This pull request introduces several improvements to the configuration check modules and related Ansible tasks, focusing on better handling of string validation and enhanced robustness in command execution for virtual machine and network checks.

String validation improvements:

• Updated validate_string in configuration_check_module.py to normalize whitespace in both expected and collected strings, making string comparisons more robust against formatting differences.
• Added the re module import in configuration_check_module.py to support the new whitespace normalization logic.

Virtual machine checks robustness:

• Modified VM checks in virtual_machine.yml to check if the mdatp command exists before running it, outputting a clear message if Microsoft Defender is not installed. This prevents errors when the command is missing. [1] [2]

Network check script improvements:

• Refactored the shell script in network.yml for listing NICs and their IP configurations to use more robust and portable shell scripting practices, including use of read -r, improved variable handling, and normalization of output for primary/secondary IPs.
