Subject: [PATCH] Replace nonexistent Appsignal.apply_request call

The `custom_error` action in the Rails 8 example apps called
`Appsignal.apply_request(request)` inside the `send_error` block. That
helper has never existed, so the block raised `NoMethodError` instead of
attaching the request to the reported error.

Use the real public helpers to attach the request context: set the
action, and add the request's params and headers. Now `/custom_error`
reports the error with its request context, as intended.
