yes indeed, gettexting is not yet complete. That's one of the reasons this is still a test-version. Things will likely still change here and there, so better to wait with the gettexting. When final version is ready, everything will be gettexted. I promise
That was my way of cheating around the problemBut text in an image Q

It's not an elegant solution, I know. But at least it gives the user a nice icon above a piece of boring info. If every user would have the latest yad version, with the html function working, problem would be solved by making "About" a small html file. Or...would yad be able to display a md file? That is your domain.
Or I could drop "About" altogether, was just mimicking the big boys.
