Actions Quickstart

As a PowerShell developer, I find GitHub Actions wildly useful and very straightforward. PowerShell is built into each of the runner images, and is supported out of the box. PowerShell has a strong CI/CD community and it makes a ton of sense to include it in the quickstart.

Actions Cache Example

Add PowerShell to the examples.md and include all appropriate directories for each OS.

Actions Workflow Examples

I understand that the repository states that GitHub is not adding new workflows at this time, but I believe PowerShell was overlooked in the original documentation, which is a common problem in our community. Fortunately, PowerShell was not looked over in the runners 🤩

GitHub documentation just went public, I am updating GitHub Action Documentation with a PowerShell example. This workflow will help me create more complete documentation for the community. GitHub has provided runners with PowerShell's testing framework, Pester, built-in and accepting this pull request will help complete the documentation for my proposed PR for adding sample.
