Bump rails from 7.1.5.2 to 8.0.4 in /spec/tester_mongo

[dependabot]

Bumps rails from 7.1.5.2 to 8.0.4.

Release notes

Sourced from rails's releases.

8.0.4

Active Support

• Fix Enumerable#sole to return the full tuple instead of just the first element of the tuple.

  Olivier Bellone

• Fix parallel tests hanging when worker processes die abruptly.

  Previously, if a worker process was killed (e.g., OOM killed, kill -9) during parallel test execution, the test suite would hang forever waiting for the dead worker.

  Joshua Young

• Fix NameError when class_attribute is defined on instance singleton classes.

  Previously, calling class_attribute on an instance's singleton class would raise a NameError when accessing the attribute through the instance.

  object = MyClass.new
  object.singleton_class.class_attribute :foo, default: "bar"
  object.foo # previously raised NameError, now returns "bar"

Active Model

• No changes.

Active Record

• Fix SQLite3 data loss during table alterations with CASCADE foreign keys.

  When altering a table in SQLite3 that is referenced by child tables with ON DELETE CASCADE foreign keys, ActiveRecord would silently delete all data from the child tables. This occurred because SQLite requires table recreation for schema changes, and during this process the original table is temporarily dropped, triggering CASCADE deletes on child tables.

  The root cause was incorrect ordering of operations. The original code wrapped disable_referential_integrity inside a transaction, but PRAGMA foreign_keys cannot be modified inside a transaction in SQLite - attempting to do so simply has no effect. This meant foreign keys remained enabled during table recreation, causing CASCADE deletes to fire.

  The fix reverses the order to follow the official SQLite 12-step ALTER TABLE
