chore: join owner, template, and org in new workspace view (#15116)

Joins in fields like `username`, `avatar_url`, `organization_name`,
`template_name` to `workspaces` via a **view**. 
The view must be maintained moving forward, but this prevents needing to
add RBAC permissions to fetch related workspace fields.
