Added missing required workflow permissions

[kartykp]

Ref: https://github.com/github/npm/issues/13757

This PR adds minimal required permissions to GitHub Actions workflows to follow the principle of least privilege and improve repository security. Previously, workflows were running with default permissions which could grant unnecessary access.

Changes Made

Workflow Permission Updates:

• [test.yml]: Added contents: read - Required for shared workflow to access repository code and configuration files
• [deploy.yml]: Added contents: read and deployments: write - Required for reading deployment configurations and creating GitHub deployments
• [codeql-analysis.yml]: Added actions: read, contents: read and security-events: write - Required for reading source code and uploading security scan results

Security Benefits

• ✅ Principle of least privilege: Each workflow now has only the minimal permissions needed for its functionality
• ✅ Reduced attack surface: Workflows cannot access or modify resources they don't need
• ✅ Explicit permissions: Clear documentation of what each workflow can access
• ✅ Security compliance: Follows GitHub's security best practices for Actions
