build: Set permissions for GitHub actions (#1369)

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 https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#permissions https://docs.github.com/en/actions/using-jobs/assigning-permissions-to-jobs [Keeping your GitHub Actions and workflows secure Part 1: Preventing pwn requests](https://securitylab.github.com/research/github-actions-preventing-pwn-requests/) Signed-off-by: naveen <[email protected]>
