Update documentation site with interactive component reference

[geoffjay]

Summary

Update the MkDocs-based documentation site to link to the Storybook for live component previews, and refresh the configuration reference to accurately reflect the current XML format.

Context

The docs site (docs/public/) has configuration and getting-started guides. Static code samples in docs/public/configuration.md should:

• Use the current XML format (not legacy HCL)
• Link to corresponding Storybook pages so readers can see components in context
• Be validated against the actual component schemas

Acceptance Criteria

• docs/public/configuration.md updated with current XML format examples
• Each component reference in the docs links to its Storybook page (e.g., /component/button)
• Storybook hosted or documented so the links are resolvable
• docs/public/getting-started.md updated with the nemo storybook command as a learning resource
• docs/public/develop.md updated with LSP/VS Code extension setup instructions
• Cross-reference added: configuration.md → architecture.md for data flow concepts
• Any HCL references in docs replaced with XML syntax
• MkDocs navigation updated to include the storybook and authoring tooling sections
