Misc 0 / docs (pull_request) Failing after 35s

Docs build is failing because of a limitation with our automation. I am going to ignore for this release branch since it is usually skipped in the cherry pick workflow run by opentelemetrybot

@lzchen I had to run tox -e generate to fix CI as well 425b332. I think this is expected and I'm assuming the Prepare Release workflow will update it to the right version when I cut the patch release?

Since openai instrumentation is released via a different workflow, it actually doesn't matter what the gen script changes the version to. In this case, it's actually "behind" on this release branch since the 2.0b0 release of openai instrumentation was already released after this release branch was created. I think you can just generate the code just to get builds to pass and it should be fine.
