[Blog] Proposal: Add categorical-tags to blogs for better navigation

[JigaoLuo]

Hi datafusion team,

First, thank you for consistently publishing high-quality blogs! I appreciate the effort behind them.

Feedback & Suggestions:
While the content is excellent, navigating the blogs can be challenging due to no indexing. It takes time to skim through release notes to find specific content topics. It would be much nicer if we could prune(filter) blogs using their tag metadata.

Example:
The DuckDB blog (news) uses a tagging navigation that works well. For instance, there are 6 tags like: using-duckdb, benchmarks, deepdive, extensions, releases,
These tags help readers quickly filter content by interest, whether they’re looking for how-to guides, technical deep dives, or release updates.
