Depending on how broad you make your definition of Azure DevOps. On Azure, it's easy to host a static content website and it's possible to link an Azure Website to a Git Repository in Azure DevOps. You can even serve a website straight from Blob Storage.
Or you can set up an Azure Pipeline to package, optionally transform and publish the content using Jekyll or Hugo.
It's not as simple as GitHub Pages, but ultimately, once set up, just as simple and eventually more powerful depending on what you want to achieve.
For publishing project documentation, you can also use Public Projects and allow guest access to the Wiki.
