DEV: Set config.eager_load = true on CI (#25032)
Why this change?

When running system tests on our CI, we have been occasionally seeing
server errors like:

```

```

While looking through various Rails issues related to the error above, I
came across https://github.com/rails/rails/pull/27647 which is a fix to
fully initialize routes before the first request is handled. However,
the routes are only fully initialize only if `config.eager_load` is set
to `true`. There is no reason why `config.eager_load` shouldn't be `true` in the
CI environment and this is what a new Rails 7.1 app is generated with.

What does this change do?

Enable `config.eager_load` when `env["CI"]` is present
