DEV: Upgrade Rails to version 7.1 (#27539)

* DEV: Upgrade Rails to 7.1

* FIX: Remove references to `Rails.logger.chained`

`Rails.logger.chained` was provided by Logster before Rails 7.1
introduced their broadcast logger. Now all the loggers are added to
`Rails.logger.broadcasts`.

Some code in our initializers was still using `chained` instead of
`broadcasts`.

* DEV: Make parameters optional to all FakeLogger methods

* FIX: Set `override_level` on Logster loggers (#27519)

A followup to f595d599dd361b7fb39fb3c82cbc11d19d518c19

* FIX: Don’t duplicate Rack response
