Docs/clarify git hub pages config required for forks

[Muneeb-Masood]

This pull request updates the deployment instructions in the PERSONALIZE.md file to clarify the steps required for enabling GitHub Actions and setting up GitHub Pages when working with a forked repository.

Deployment process clarification:

• Updated instructions to specify that, before pushing to the default branch, users must enable workflows in the Actions tab of the forked repository and change the GitHub Pages source to "GitHub Actions" in the repository settings. This ensures the workflow can deploy to GitHub Pages successfully.
