docs: fix broken vLLM engine arguments docs link in vllm.mdx

[sanjibani]

Summary

Single link fix in docs/customize/model-providers/more/vllm.mdx:6.

The vLLM provider documentation references the vLLM engine arguments page at a URL that returns 404:

https://docs.vllm.ai/en/latest/usage/engine_args.html

vLLM reorganized their docs and moved the engine arguments page under /configuration/:

https://docs.vllm.ai/en/latest/configuration/engine_args.html

Verification

• Old URL: HTTP 404 (curl HEAD + GET)
• New URL: HTTP 200, page renders vLLM's engine arguments reference

The 'server documentation' link above this line (/serving/openai_compatible_server.html) still returns 200 and was not changed.

Summary by cubic

Update the vLLM provider docs to point the “engine arguments” link to the new /configuration/engine_args.html path. This fixes the 404 and sends readers to the correct reference page.

^{Written for commit 277c059. Summary will update on new commits.}
