chore: Set permissions for GitHub actions (#2555)

* chore: Set permissions for GitHub actions

 Restrict the GitHub token permissions only to the required ones; this way, even if the attackers will succeed in compromising your workflow, they won’t be able to do much.

- Included permissions for the action. https://github.com/ossf/scorecard/blob/main/docs/checks.md#token-permissions

* Update docs-production-deploy.yml

* added `packages: write` permissions

this is apparently needed by GH so this repository can push new images.
