WCAG Issues action

This GitHub action is built with a couple techniques and libraries, if you want to know more about them check out these web pages:

• GitHub Artifact @actions/artifact library, for sharing the resulting JSON file as GitHub Artifact.
• GitHub Action @actions/core library, for reading the arguments from the action YAML.
• GitHub octokit.js library, for getting information about issues in the GitHub API.
• Expressing ACT Rule results with JSON-LD and EARL: the JSON format we use for output.
