Subject: [PATCH] Add explicit read permissions to workflows

Motivation:

* More secure GitHub Actions workflows

Modifications:

Add explicit 'contents: read' permissions to workflows that did not have
explicit permissions defined. This follows GitHub Actions security best
practices by limiting the default GITHUB_TOKEN permissions.

Result:

An extra layer of security.
