Preinstall gh cli

Feature Request

Description

Adding the GitHub CLI (gh) to the self-hosted runner environment would align it more closely with the setup provided in GitHub-hosted runners. This addition would allow users to leverage the gh CLI directly in self-hosted environments, providing seamless compatibility with scripts and workflows that depend on GitHub's command-line tools.

Context

The GitHub CLI is widely used and referenced in GitHub Actions documentation, making it a familiar tool for users who are scripting or automating tasks within GitHub Actions workflows. For new users especially, having gh available by default in both GitHub-hosted and self-hosted runners would simplify their learning curve and promote consistency across environments.

Additionally, many existing workflows and actions rely on gh for tasks like managing issues, pull requests, and repositories, meaning this addition could increase compatibility and reduce setup time for teams adopting self-hosted runners.
