chore: Set permissions for GitHub actions

[naveensrinivasan]

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
