Workflows will fail if missing custom secret infra_automation

[Aditya30ag]

Problem

Some workflows (test_and_deploy.yml and issue_assignment.yml) rely on a custom secret secrets.infra_automation.
If this secret is not configured in the repository, the workflows fail at runtime.

Why this matters

• Introduces a hidden dependency on a repo secret
• Causes workflow failures for new contributors or forks
• Harder to maintain than GitHub’s built-in token

Suggested Solution

• Replace secrets.infra_automation with ${{ secrets.GITHUB_TOKEN }}
• Add explicit workflow-level permissions for required scopes (e.g., issues, pages, contents)

Benefits

• Reduces failure surface
• Follows GitHub best practices
• Improves maintainability and security
