This is a first step towards improving our docs release process. The
goal here is to get rid of the manual "publish docs" step. This is done
as a periodic check because we only want to run this for "published"
releases, i.e. the ones that are not marked as prerelease. Because the
act of publishing a release is a manual step that Azure cannot trigger
on, we instead opt for a periodic check.
Not included in this piece of work:
- Any change to the docs themselves; the goal here is to automate the
current process as a first step. Future plans for the docs themselves
include adding links to older versions of the docs.
- A better way to detect docs are already up-to-date, and abort if so.
- Including older versions of the docs.
- Switching the DNS record from the current AWS S3 bucket to this new
GCS bucket. That will be a manual step once we're happy with how the
new bucket works.
