Potential fix for code scanning alert no. 5: Workflow does not contain permissions

As part of the organization's transition to default read-only permissions for the GITHUB_TOKEN, this pull request addresses a missing permission in the workflow that triggered a code scanning alert.

This PR explicitly adds the required read permissions to align with the default read only permission and is part of a larger effort for this OKR github/security-services#455
