Publish docs to s3 uses current version of workflows/scripts

In case we built docs for past version of airflow we checkout
both - current (main) version of code to use latest environment
and tag version of code to build the documentation. The workflow
mixed sub-workflows and run them from the "tag" version of workflow
rather than from current.

This PR fixes it.
