[studio] Update Studio's install.sh to use hab only.

This change introduces a new `habitat-sh` S3 bucket with a copy of a
recent `core/hab-static` artifact. The installer has also been updated
to immediately upgrade to the current release of `core/hab-static` in an
effort to keep things current for as long as possible.
