I created a new project using the Ruby on Rails project template. The latest Rails version currently is `6.0.2.1`, but my new project came with version `5.2.0`. I would expect to have the latest version when starting a new project, but what's worse is that `5.2.0` have known security vulnerabilities. :scream_cat:
Project templates need to be kept up-to-date. Updating them manually one by one and checking its dependencies is not feasible. We need to find a way to automatically update dependencies and all of our existing project templates.
