Make code-snippet modal resuable in Security Configuration

Related Issue - #330721 (closed)

What does this MR do?

This MR makes ConfigurationSnippetModal reusable by adding a prop scanType.

Why

ConfigurationSnippetModal component is currently being used for API Fuzzing Configuration. We plan to use the similar modal for DAST Configuration (by #330721 (closed)), and reusing the component will

• avoid code duplication
• when we add features like Syntax highlighting, it will apply to both configurations
