docs: add Pinstripes as OpenAI-compatible LLM provider

[max-amos]

Summary

Adds Pinstripes to the LLM provider configuration examples in docs/edge/en/concepts/llms.mdx.

Pinstripes is an OpenAI-compatible inference API. CrewAI already documents this pattern for other providers (Perplexity AI, Open Router, local NVIDIA NIM) — Pinstripes slots in using the same openai/<model> prefix + base_url via LiteLLM.

Changes

• New Pinstripes accordion in docs/edge/en/concepts/llms.mdx under the Provider Configuration Examples section
• Includes: environment variable setup, Python code example, model table with pricing for all four available models

Models covered

Model	Price/1M tokens
openai/ps/deepseek-v4-flash	$0.10
openai/ps/glm-4.5-air	$0.125
openai/ps/qwen3-35b	$0.14
openai/ps/minimax-m2.7	$0.255

Notes

• Documentation-only change, no code or dependency changes
• Uses the same LiteLLM openai/ + base_url pattern already documented for Perplexity AI and Open Router
• llm-generated label applied per CONTRIBUTING.md requirement

Summary by CodeRabbit

• Documentation
  • Added Pinstripes LLM provider documentation with setup instructions, configuration examples, available models with per-token pricing, and guidance for using models via LiteLLM.

📝 Walkthrough

Walkthrough

A new "Pinstripes" provider accordion is added to the LLM concepts documentation page. It covers the PINSTRIPES_API_KEY environment variable, an LLM configuration sample using an OpenAI-compatible base_url, a table of available models with per-token pricing, and the requirement to use the openai/ LiteLLM prefix.
