Warning!!

The AP CSP Create Performance Task is in progress from April 1 - May 1 2023. Please
consider any risk introduced by this PR that could affect our students taking AP CSP. Code.org
students taking AP CSP primarily use App Lab for their Create Task, however a small percent use Game
Lab. Carefully consider whether your change has any risk of alterering, changing, or breaking
anything in these two labs. Even small changes, such as a different button color, are considered
significant during this time period. Reach out to the Student Learning team or Curriculum team for
more details.

Create new feedback strings for validating Sprite Lab levels. These strings are from 4/19 updates.
