We're disabling `action_controller.raise_on_missing_callback_actions`
because sometimes we include `before_action :something, only: actions`
in concerns, and we include these concerns in controllers that don't
have all these actions.
Note that Rails 7.1 logs to STDOUT by default [1]; we're re-adding the
condition `if ENV["RAILS_LOG_TO_STDOUT"].present?` because we're still
using files and we're rotating the logs to avoid running out of space.
Also note that the GraphQL controller test (which is actually a request
test, since it's got `type: :request`) that was raising an exception no
longer does it thanks to the new default value for the
`config.action_dispatch.show_exceptions` configuration option. So we're
updating the test accordingly. This option doesn't affect regular
controller tests (without the `type: :request` option), so in other
tests we're still checking exceptions.
