Description
Add markup to the ProgramBlockEditor to ensure that the Robot character is perceivable by screen reader. Make it into a heading so that it is part of the page structure. Something along the lines of:
<h3>
<span role='img' aria-label='robot character'>
<RobotIcon/>
</span>
</h3>
Notes:
- Retrieve the "robot character" string from the localized messages file
- Verify that the image is perceivable by screen reader
