[no-jira] update ruby 3.3.5 and rails 7.0.8.7

[dbenton9]

In order to satisfy technical debt upgrade heroku I first need to update ruby and rails versions compatible with current heroky stacks.

This PR brings ruby up to 3.3.5 and rails to 7.0.8.7.

This is my first ever attempt at a ruby/rails upgrade but the app still runs locally. I'm taking that as a good sign 😅

Justin's Notes for Rails 7 upgrade

Rails 7 upgrades:

• Gemfile updates from railsdiff.org
• bundle update rails & fix dependencies
• railsdiff for config/environments/development.rb
• rails app:update
• railsdiff
  • note if cookies_serializer.rb uses marshal, use hybrid instead (see new_framework_defaul)
  • leave package.json for now
• add importmaps if needed: bin/rails importmap:install
  • pin JS dependencies: bin/importmap pin library@version
  • add to app/javascript/application.js
• remove webpack files (contents of .gitignore, .iyarc, babel.config.js, package.json, postcss.config.js, yarn*, node_modules, config/webpack, config/webacker.yml, public/packs) https://guides.rubyonrails.org/upgrading_ruby_on_rails.html#upgrading-from-rails-6-1-to-rails-7-0
  • button_to check (2.1)
  • encrypted cookies check (2.10)
  • ActiveStorage variants check (2.14)
• Check for open redirects: (redirect_to , allow_other_host: true)
• Check for link_to with method (switch to button_to or use turbo)
• Add vips to dockerfile if necessary; remove imagemagick, nodejs, yarn
• GHA workflow - remove yarn checks; add importmap audit
