Dear maintainer, below is a concise technical summary of the changes proposed in this PR:

Implement a new check AppServiceIPResctrictionDefaultActionSCMDeny to ensure that the default IP restriction action for SCM in Azure App Services is set to 'Deny'. This check is integrated into the Checkov framework and applies to both azurerm_linux_web_app and azurerm_windows_web_app resources. The check inspects the site_config block for the scm_ip_restriction_default_action key. Additionally, test cases are added to verify the functionality of this check, ensuring it correctly identifies compliant and non-compliant configurations.
