Data Feeds: Precision updates, key terms page + cross linking, overview page restructure

[dev-dist]

This pull request expands and updates the documentation for Chainlink Data Feed types, adding new feed categories and detailed explanations for each. It also updates the sidebar navigation to include a new section for key terms and concepts.

Documentation updates and enhancements:

• Expanded feed types and descriptions: The feed-types.mdx file now includes two new categories—Tokenized Equity Feeds and 24/7 Extended-Hours Data Feeds—with detailed descriptions and links to their respective documentation. The overview table and keywords have also been updated to reflect these additions.
• Detailed explanations for each feed type: The documentation now provides individual sections for each feed type (Price Feeds, Tokenized Equity Feeds, SmartData Feeds, SVR Feeds, Rate & Volatility Feeds, L2 Sequencer Uptime Feeds, 24/7 Extended-Hours Data Feeds, and Self-Managed Feeds), offering clear guidance and links to further resources.

Navigation improvements:

• Sidebar update: The sidebar configuration now includes a new entry, "Key Terms and Concepts," under the Data Feeds section to help users find essential terminology and conceptual information more easily.
