Add CI workflow to deploy a versioned MkDocs-based website to GitHub Pages
On every push to the repository's default branch or release branch, deploy the repository's MkDocs-based static website to GitHub Pages. Documentation content will sometimes apply only to a specific version of the project. For this reason, it's important for the reader to be able to access the documentation for the specific version of the project they are using. The documentation system provides access to: - The tip of the default branch ("dev") - The latest release ("latest") - Each minor version series (e.g., "1.2") The website version is selectable via a menu on the website as well as the URL of each documentation page.
