Read the Docs Pro Plan

I’m trying to get the read the docs check to pass for my PR #28791. It seems that the maximum concurrency limit (4) has been reached. The build automatically retries every 5 minutes, but according to https://app.readthedocs.org/projects/vllm/builds/?version__slug=&state=active&version__type=, it seems that PR #25438 has been stuck in the queue for 3-4 days. Given that, would it be a good idea for vllm to upgrade to the pro plan for read the docs, which increases the concurrency limit from 4 to 6?

We actually already do have an increased concurrency limit. It seems as though this one in particular got stuck rather than legitimately being in the queue for that long.
