How to upgrade this repo

From time to time you may want to upgrade either Ruby or Rails versions. To do so, remove all files but:

• Gemfile
• Dockerfile
• docker-compose.yml
• init.sql
• .devcontainer

Overwrite the current Gemfile with the desired new versions and using the Dev Containers extension, Repoen in Container. Here's an example:

source 'https://rubygems.org'

ruby '3.2.2'

gem 'rails', '~> 7'

Once in the container, run rails new or whatever command you need in order to generate a new app skeleton. Commit changes.
