DOC-6724 added RDI Cloud section to on-prem landing page

[andy-stark-redis]

Note

Low Risk
Documentation-only additions under content/develop/ai/redisvl/0.18.2/ with no runtime or infrastructure changes.

Overview
Adds a new RedisVL 0.18.2 documentation tree under content/develop/ai/redisvl/0.18.2/, including a version landing page and Hugo API reference pages wired to /develop/ai/redisvl/0.18.2/.

The API index expands the published surface versus older version trees: index stopwords and SVS-VAMANA schema topics, plus reference pages for query (including HybridQuery, SQLQuery, runtime tuning on vector queries), LLM cache (SemanticCache, LangCache managed cache, EmbeddingsCache), filters (e.g. tag wildcard matching), message history, rerankers, and semantic router.

Content is generated-style API docs (signatures, parameters, cross-links via relref); no application or library code changes in this diff.

This relref isn't live yet - it's currently operate/rc/databases/rdi, but is moving for RDI Cloud GA (#3383).

Approving with BIG caveat about current link to relref - though it looks like your ticket mentions that this needs to go live with RDI Cloud GA stuff next week. If you want, you can set the base branch to my RDI Cloud GA branch, that way it'll all merge together.

Good idea - done.
