Rewrite NLWEB documentation with comprehensive content

[Copilot]

The NLWEB.md file contained only placeholder content (title, "Some text here", and a localhost iframe). Replaced with full documentation explaining NLWeb's purpose and applicability to data wrangling workflows.

Changes

• Core content: Documented NLWeb as Microsoft's open-source natural language web interface project, explaining conversational querying, structured data integration (Schema.org, RSS, JSON-LD), and LLM/vector database flexibility

• Wrangles context: Added "Why NLWeb for Wrangles?" section connecting natural language interfaces to data transformation discovery, with example queries like "How can I extract addresses from text?" and "Show me examples of standardizing phone numbers"

• Use cases: Segmented by persona (Data Engineers, Business Analysts, Developers) with specific workflows for each

• Resources: Linked to official NLWeb site, GitHub repo, and Microsoft announcement

• Title casing: Fixed "Nlweb" → "NLWeb"

Preview

The documentation now provides actionable context for how natural language interfaces enhance documentation discovery and AI-agent accessibility for Wrangles workflows.
