[JetStream] Movie card titles are no longer horizontally constraint.

In the recent pull request https://github.com/android/tv-samples/pull/142 the explicit [width](https://github.com/android/tv-samples/pull/142/files#diff-0ce80aeb4da37b43fd50dec1fb00c50172fb17b2be0d95701fcabaa9669513fdL241) was removed from the modifier on the `StandardCardLayout` in the `common/Moviesrow.kt` file. This will cause the card to horizontally expand as needed to place the title of the item on the screen.

It is generally not noticeable in the sample as all the movie titles in movies.json are small enough but as the screenshot below shows longer titles will cause issues.


Start in common/Moviesrow.kt at the StandardCardLayout modifier, then compare the related change in pull request 142. Verify the behavior with a movie title longer than those in movies.json; done means the card keeps a constrained width and the title no longer expands the card horizontally.
