[aduth]

🛠 Summary of changes

Updates Rails from 7.1.4.1 to 7.2.1.1.

CHANGELOG:

• 7.2.0 (see upgrade notes)
• 7.2.1
• 7.2.1.1

Edit: This was originally targeted at resolving security advisories, but this was addressed separately in an incremental update in #11358.

📜 Testing Plan

Verify that build passes and application runs without warnings or errors.

The upgrade to 7.2 was more involved than first expected, specifically due to removals of deprecations, notably the removal of preview_path= from ActionMailer (which also affected dependency rspec-rails), as well as deprecated removal of ActiveRecord::Migration.check_pending!.

I reviewed all "Removals" and "Deprecations" from the 7.2 release notes to check for anything that might affect us, but would suggest reviewers do the same.

Failing test for lib/data_pull.rb appears to be affected by this change: https://blog.saeloun.com/2024/05/30/rails-7-2-pg-adapter-to-type-cast-date/

I tried to include another bundle update rails to catch transitive dependency updates, but there were a lot of failing specs (see build). Not clear which of the dependencies caused the issue, but I reverted back to the original Gemfile.lock updates and rebased against main.

For posterity, the changes attempted are reflected here: https://github.com/18f/identity-idp/compare/834aaf62b86e75faf6076524bc2eac66ac8f7baf..68eba3effc8a84d7d3c5e52927fdc4ba268de2ba

If I were a betting person, the rack update is the one I'd think might be the issue.
