Potential fix for code scanning alert no. 18: Workflow does not contain permissions

[DaTiC0]

Potential fix for https://github.com/DaTiC0/smart-google/security/code-scanning/18

To fix the problem, add an explicit permissions block defining the least privileges needed for this workflow. This job merges main into container and pushes back to the repository, so it needs write access to repository contents via GITHUB_TOKEN. It does not appear to need other scopes (e.g., no issues, PRs, or packages operations are present), so we can restrict it to contents: write.

The best way to fix this without changing functionality is to add a permissions block at the job level under merge-branch:. That way, only this job is granted contents: write. Specifically, in .github/workflows/sync-main-to-container.yml, under jobs:, after the merge-branch: line and before runs-on: ubuntu-latest, add:

    permissions:
      contents: write

No additional imports, methods, or definitions are required, since this is a YAML GitHub Actions workflow file; the permissions key is standard syntax.

Suggested fixes powered by Copilot Autofix. Review carefully before merging.
