config.google_cloud.use_logging/debugger/trace等の設定を入れていたらbundle installやminitest実行に失敗した話

## 3行で書くと

* `config.google_cloud.use_logging = false` 等の設定を入れていると `$ bundle install` や `$ rails test`（minitest）が通らなくなることがあった[^1]
* その設定をそのまま外したら通った
* その設定を入れた理由の事象も解消されていたので恒久的に外したままで大丈夫そう


## 環境

Windows 10 Pro、Ruby3.2.2、Rails7.1.2


## 経緯

Gemfileの、主にGoogle Cloud絡みのものをガチャガチャ弄っていたらある時 `$ bundle install` や `$ rails test`（minitest）が通らなくなってしまいました。

（上記以外のエラーが出た時もあった気がしますが記録がなく不明）

```:rails testのエラー
C:/Ruby32-x64/lib/ruby/gems/3.2.0/gems/railties-7.1.2/lib/rails/railtie/configuration.rb:109:in `method_missing': undefined method `google_cloud' for #<Rails::Application::Configuration:0x00000000002e90> (NoMethodError)
```
rails s とかでも出るかもしれません

調べてみたらあまり情報はなかったんですが、古い情報ながら下記に行き当たりまして

https://github.com/googleapis/google-cloud-ruby/issues/1860

話の本筋はだいぶ違うような気はするものの、どうも `config.google_cloud.use_logging` 辺りが怪しそう。
確かにgcloud CLI のインストール・セットアップ後、あらゆる `rails` コマンドで警告が出ていたため（下記記事と同事象）

https://qiita.com/yjiro0403/items/88d078b52fa8707f7289

これに倣って `config/enviroments/` 以下の `development.rb` `test.rb` に下記の設定を入れていました。
```ruby
config.google_cloud.use_logging = false
config.google_cloud.use_debugger = false
config.google_cloud.use_error_reporting = false
config.google_cloud.use_trace = false
```

ならば一旦こいつらを消してみようと、設定前の状態に戻してみたら

* エラーは解消し、`$ bundle install` も `$ rails test` も通った
* そして当初の警告も何故か表示されなくなっていた

ので、再現条件や発生理由等掘り下げていないですしその予定もないのですが
もし同じ事象で困っている方がいれば一助になれば幸い🙏ということで一応記事にしておきました。
