[actions] weekly GitHub action to trigger stable update (#1213)

This PR adds a weekly GitHub action that automatically creates stable update issues every Monday, following the format specified in the requirements.

## What this PR does

Creates a new GitHub workflow (`.github/workflows/weekly-stable-updates.yml`) that:

- **Runs automatically every Monday at 9:00 AM UTC** using a cron schedule
- **Creates issues with the correct title format**: "Stable Updates YYYYMMDD" (e.g., "Stable Updates 20250717")
- **Includes all required commands** in the issue body:
  ```
  dotnet cake -t:update-config
  dotnet cake utilities.cake -t=generate-component-governance
  dotnet cake utilities.cake -t=generate-namespace-file
  dotnet cake utilities.cake -t=list-artifacts
  ```
  And:
  ```
  dotnet cake utilities.cake -t=api-diff-markdown-info-pr
  ```
- **Automatically assigns issues to @copilot-swe-agent**
- **Supports manual triggering** via workflow_dispatch for testing

## Issue format

The created issues will match the format from [issue #1202](#1202), containing step-by-step instructions for updating Android library bindings and generating necessary governance files.

## Testing

The workflow has been validated for:
- ✅ Correct YAML syntax
- ✅ Proper date formatting (YYYYMMDD)
- ✅ Exact command matching per requirements
- ✅ GitHub Actions best practices

Context #1212.
