docs(library): update what-is-retrieval-augmented-generation

[icecrasher321]

Content update to apps/sim/content/library/what-is-retrieval-augmented-generation: Full replacement. Replace the entire existing article body with the supplied replacement article. Keep the existing slug, folder, title, and frontmatter date unchanged. Migrate the 'Frequently asked questions' section out of the body into the frontmatter faq array with all 5 entries verbatim as plain text, and remove that heading from the body. Set updated to today's date and recompute readingTime.

Greptile Summary

Updates the retrieval-augmented generation library article with revised explanations, comparisons, links, tradeoffs, and calls to action.

• Sets the updated date to 2026-09-06 and adjusts the reading-time metadata.
• Keeps five FAQ entries in schema-valid frontmatter.
• Clarifies semantic, keyword, hybrid, and agentic retrieval concepts.
• No diagram is included because this documentation-only wording update does not introduce a new system flow or architecture that would benefit from one.

Confidence Score: 5/5

The documentation update appears safe to merge with no actionable correctness, rendering, security, or repository-rule issues identified.

The revised frontmatter conforms to the content schema, all internal article targets exist, and the changed Markdown is supported by the repository's MDX compilation pipeline.
