Potential fix for code scanning alert no. 1: Workflow does not contain permissions

[brunosan]

Potential fix for https://github.com/Clay-foundation/model/security/code-scanning/1

To fix the problem, we should explicitly add a permissions block to the build-book job in the .github/workflows/deploy-docs.yml workflow, granting it only the minimal privilege required, which is contents: read. This prevents the job from inheriting potentially excessive default permissions from the repository or organization, adhering to the principle of least privilege. This change is made in the job definition for build-book, ideally immediately after runs-on: ubuntu-22.04 (line 26). No new imports or method definitions are necessary; this is a configuration fix within the YAML file.
