[MISC] Add code owners of vllm/v1 to vllm/v1/core

[heheda12345]

Purpose

As /vllm/v1/core overrides /vllm/v1, only I am tagged for PRs that only touches /vllm/v1/core (e.g., #24926). But I don't have the expertise to review all PRs in this folder, so add more people.

Code Review

This pull request updates the .github/CODEOWNERS file to add more owners for the /vllm/v1/core and /tests/v1/core paths. The goal is to distribute the review load for this critical part of the codebase, as explained in the description. The change is straightforward and correct, improving the project's maintainability. I approve this change.

Maybe @njhill can join the sampler-gang? :)

@22quinn I mean is this line overridden by the line for /vllm/v1?

Yeah, sampler is good for @njhill, @22quinn and me. cc: @heheda12345
