Streamlining Drupal and WordPress with GitLab and Pantheon

What this post added

This post details the technical steps and configuration required to integrate GitLab CI/CD with Pantheon for automated deployments. It covers setting up SSH keys for secure access between GitLab and Pantheon, configuring GitLab CI/CD variables for Pantheon site name and Git URL, and defining a `deploy:dev` job in `.gitlab-ci.yml` to push code from the GitLab `master` branch to the Pantheon development environment. It also outlines the process for setting up Pantheon Multidev environments for merge requests, enabling on-demand deployments for independent work and QA.
