Migrate pytorch_python_doc_build to github action (#57371)
Summary:
# Changes
This PR migrates `pytorch_python_doc_build` from circleci to github actions.
Noticeable changes
- Refactor `docker cp` into a single `docker run` with volume mount, because the in circleci volume is not accessible from its remote docker engine
- `pytorch_python_doc_push` job will have a race condition with circleci, which will be migrated in separate PRs
