docs: list the TH-8103 integrations in the README catalogs - #250

Summary

Align the root and Python README catalogs with the integration source on dev after the TH-8103 integration merges. Merge this catalog PR last.

• List all 64 Python framework packages using their actual package metadata names, plus the core library and one-line setup SDK.
• List the 44 TypeScript framework packages and two core/conventions packages, 23 Java integration modules and Java core, four Go modules, and the C# tracing library.
• Link package names directly to their checked-in source and setup guidance, without implying a package-registry release.
• Separate provider/framework packages from recipes: Anannas AI, Azure AI Foundry, Cognee, Databricks, Doubleword, EverOS, Gradio, LangSmith, NVIDIA DGX Cloud Lepton, MLflow, OpenInference, OpenLIT, OpenLLMetry, OrcaRouter and PrismML Bonsai; also link Deep Agents via LangChain, TanStack AI, Arconia, Quarkus LangChain4j and Open WebUI.
• Derive the framework-specific language matrix from the same package inventory. Describe C# generic tracing separately, and include the existing Go modules rather than leaving Go on the roadmap.
• Keep the Python README's package list consistent with the root catalog and correct the core installation package name to fi-instrumentation-otel.

Only README.md and python/README.md differ from the current dev integration baseline. Runtime code and dependencies are unchanged.
