Make dbt-sql and default-sql templates public (#1463)

## Changes

This makes the dbt-sql and default-sql templates public.

These templates were previously not listed and marked "experimental"
since structured streaming tables were still in gated preview and would
result in weird error messages when a workspace wasn't enabled for the
preview.

This PR also incorporates some of the feedback and learnings for these
templates so far.
