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

[adhami3310]

Potential fix for https://github.com/reflex-dev/reflex-azure-auth/security/code-scanning/1

In general, the fix is to explicitly declare a minimal permissions block in the workflow so the automatically provided GITHUB_TOKEN has only the scopes required. For this workflow, the job just checks out code and runs pre‑commit locally, so it only needs read access to repository contents.

The best fix without changing existing functionality is to add a permissions section scoped to the pre-commit job (or at the root). To keep the change minimal and localized to the flagged region, we’ll add it directly under pre-commit: in .github/workflows/pre-commit.yml. We’ll set contents: read, which is sufficient for actions/checkout and running checks. No additional imports or methods are needed since this is a YAML workflow definition.

Concretely: in .github/workflows/pre-commit.yml, under jobs: pre-commit:, insert a new permissions: block before timeout-minutes: 30, indented to match job-level keys. No other lines need to change.
