Add Awesome RAG Production to Other Collections

[Yigtwxx]

Description

Added Awesome RAG Production to the Other Collections section.

Awesome RAG Production is a curated collection of battle-tested tools, reference architectures, and best practices for building, scaling, and monitoring production-grade RAG systems. It complements the existing collections in this section with a production/operations focus:

• Reference architectures (dev/local, mid-scale, enterprise/high-scale)
• Vector databases, embedding models, chunking, retrieval & reranking with comparison tables
• Evaluation, observability, caching, security, and FinOps for RAG
• Evidence-tagged benchmarks ([3P]/[V]/[A] source tags with methodology citations)

The repository is actively maintained and follows awesome-list standards. Entry matches the existing format of the section.
