Issue on weekly-executed GitHub workflow

Problem:

• weekly-contributions.yml, whose name is Update Attributions Weekly, does
  1. actions/checkout@v2
  2. actions/setup-node@v1
     but nothing else after.
• weekly.yml, whose name is Weekly issue updates, does
  not only Update all the translation issues on a nightly basis,
  but also Updates the attribution.json file in git.

Proposed Solution:

To make things clear,

• Separate two jobs into two yml files, or
• Change the name of weekly.yml to represent two jobs.

Files to Update:

• weekly-contributions.yml
• weekly.yml

.github/workflows/weekly-contributions.yml と .github/workflows/weekly.yml を読み始め、それぞれの名前、ジョブ、トリガー、ステップを比較します。どの workflow が attribution の更新を処理し、どの workflow が翻訳 issue の更新を処理するのかを確認します。両方のタスクの動作を変更せずに、workflow の名前とファイル構成がそれぞれの責務に明確に対応していれば完了です。
