actions: publish release docs to correct folder
actions: publish release docs to correct folder

We have been publishing docs to the wrong folter on AWS S3. We still had
the official docs published to the correct place manually though, so all
was good.

This change will eliminate the manual step of publishing documentation
and will put things where they belong.
