Azure Activity: Hunting Query Documentation Enhancement for Custom Script Extensions

What Changed

Enhanced documentation for the Rare Custom Script Extension hunting query, adding clarification about protected settings behavior and removing formatting inconsistencies.

Documentation Improvements

• Added explanatory note about protected settings encryption: when fileUris and commandToExecute are configured under Protected Settings, their values appear masked in AzureActivity logs by design
• Clarified that execution details must be reviewed from Guest VM logs rather than AzureActivity when protected settings are used
• Included reference link to Microsoft documentation
• Fixed minor formatting issues in description text
