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

Start by reading .github/workflows/weekly-contributions.yml and .github/workflows/weekly.yml, comparing their names, jobs, triggers, and steps. Confirm which workflow handles attribution updates and which handles translation issue updates. Done means the workflow names and file structure clearly match their responsibilities without changing either task's behavior.
