Upgrade rails to ~> 7.1

[heratyian]

I'm writing a lesson on async jobs using Solid Queue and Mission Control. Mission Control requires rails ~> 7.1. Soild Queue is really nice since it uses db tables instead of redis, which makes deployments simpler/cheaper. Also, you can run it on sqlite which means you can still use codespaces.

Any plans to upgrade the rails version?

Going to work on this soon, couple of notes to self:

After the Rails 7.1 update, can you ensure that there are no deprecation warnings when e.g. bundle install or rails c or rails s?
Also, it feels to me like it takes a long time to set up a codespace for the Rails 7 Template, longer than homeworks. Is that true, and if so why?
