Prevent automatic GH Pages deployments from feature branches

Adds a condition to the GitHub Pages deploy job to prevent it from running automatically when the branch name contains a hyphen. This typically filters out feature or development branches, ensuring that only designated branches (e.g., `main`) or manual workflow dispatches trigger a deployment. This avoids unintended releases of incomplete or development content to GitHub Pages.
