Subject: [PATCH] docs: note openai dep for DeclineLLMEval in LLM quickstart

DeclineLLMEval defaults to provider=\"openai\". A fresh environment that
only runs `pip install evidently` then hits ImportError when following
the quickstart. Document `pip install evidently openai` (lightweight)
instead of requiring the heavier evidently[llm] extra.

Fixes #1898

+Install the Evidently Python library. The OpenAI-backed LLM judges in this
+quickstart (for example `DeclineLLMEval`, which defaults to `provider="openai"`)

+examples — you do not need the heavier `evidently[llm]` extra (which pulls

 ```python
-!pip install evidently

+If you only need deterministic descriptors (`Sentiment`, `TextLength`,
