Update language testing experimental title

We have the advanced read aloud 0370 title which has German, French, and Italian. We want to make a number of changes to this title:
* We want to add several more languages. Richard and Prashant can get together to figure out what they should be. We want to avoid complexity by adding right to left languages at this time.
* The MathML example should be updated. The example does not make it clear thif MathML is being rendered. We want an example that will make it crystal clear that MathML is being presented. Richard will get together with neil to identify appropriate expressions.
* The reading of alt text test should also make it clear that reading systems only pass when there is the option to turn the reading of Alt text on or off.
* The name of the title should be updated. We want the most meaning ful information at the beginning of the title, and perhaps at the end indicate that it is experimental.
* We also talked about better cover images, which may make it easier to identify the title.
