Reverts #6828

@DarkLight1337, we need to revert this and reapply this later to accelerate #6797 to be landed this week. Sorry about the back and forth.

👋 Hi! Thank you for contributing to the vLLM project.
Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which consists a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of default ones by unblocking the steps in your fast-check build on Buildkite UI.

Once the PR is approved and ready to go, please make sure to run full CI as it is required to merge (or just use auto-merge).

To run full CI, you can do one of these:

• Comment /ready on the PR
• Add ready label to the PR
• Enable auto-merge.

🚀

looks like you need to rerun mypi

i'm actually confused why this failed.

I'm guessing that vllm/server was explicitly added to the list of things for mypy to check with a later commit

(It's currently in pyproject.toml)
