Windows Shared Runners beta now available on GitLab.com

Introduces Windows Shared Runners on GitLab.com, offering a managed, auto-scaling, and secure environment for Windows CI/CD jobs. These runners are pre-configured with software like Chocolatey, Visual Studio 2019 Build Tools, and .Net Framework. Each job runs in an isolated VM instance that is deleted after completion. The post details the technology overview (custom executor, per-job VM isolation), pricing (same as Linux initially), and provides a `.gitlab-ci.yml` example for usage. It also outlines limitations such as longer provisioning times and the absence of the Docker executor for Windows VMs.
