Update vllm to include 0.18.1

[Daniel-Schenker]

Description

This PR updates the vllm upper bound in pyproject.toml to include version 0.18.1.

Questions:

1. I kept it as a < operator and moved the upper bound to 0.18.2 to abide by the comment that is there. If that was the wrong choice let me know and I can switch it to <=0.18.1.
2. I ran a uv sync --upgrade-package vllm but nothing in uv.lock changed... Is there something else I should run instead?

I ran a uv sync --upgrade-package vllm but nothing in uv.lock changed...

vLLM is built from source so there's another spot with the version:
https://github.com/vllm-project/vllm-spyre/blob/85924e4b9fe91ecce7e023e892938a222bdc6d53/pyproject.toml#L87

After you update that line too, uv sync should bring in updates to uv.lock.

That did the trick. Thanks @tjohnson31415

I believe https://github.com/vllm-project/vllm-spyre/blob/main/.github/workflows/test.yml#L77 should be updated too

🤔 In this case 0.18.0 is still the lower bound since we didn't pull it up, so the vLLM:lowest entry should probably remain as 0.18.0?

spyre-ci tests passed
Normally we would bump the lower bound, but it doesn't really matter when there are no code changes / compat to deal with.
