Documentation on how to use copilot-cli in Actions

Describe the feature or problem you'd like to solve

What is the recommended method of using copilot-cli within GitHub Actions?

Proposed solution

I currently use Opencode/Claude Code in GitHub Actions to perform very specific actions with AI coding agents. I'd love to use GitHub Copilot instead to do that with copilot-cli.

Example prompts or workflows

• GitHub Action to add specific documentation in every PR
• GitHub Action to add templated information in a repo (like AGENTS.md)
• GitHub Action that verifies a task is completed within the code in PRs

Additional context

• Claude Code's docs for the same feature: https://docs.claude.com/en/docs/claude-code/github-actions
• Opencode's docs for the same feature: https://opencode.ai/docs/github/
• OpenAI's Codex CLI for the same feature: https://github.com/openai/codex/blob/main/docs/advanced.md#non-interactive--ci-mode
