GitHub API Notification Plugin for reg-suit

This plugin for `reg-suit`, a visual regression testing CLI, sends notification results to GitHub repositories. It is specifically designed for GitHub Enterprise users, utilizing the GitHub API with a personal access token for authentication, differentiating it from `reg-notify-github-plugin` which relies on a GitHub App for `github.com`. The current stable version is 0.14.6, with minor releases occurring actively as indicated by recent changelog entries. Key features include configurable GitHub URL, repository owner and name, private access token, and options for customizing the PR comment style, such as a short summary table. It's an essential component for integrating `reg-suit` results into GitHub-centric CI/CD workflows, especially in enterprise environments where GitHub Apps might be restricted.
