Describe the bug
The unsupported block UI test uses the Audio block as an unsupported block, however this block is recently supported so the test fails.

CircleCI test failures:

• Test iOS on Device - Scheduled
  
• Test Android on Device - Scheduled

To Reproduce
This bug can be reproduced locally by running the specific UI test:

• For iOS run: npm run test:e2e:ios:local gutenberg-editor-unsupported-blocks.test
• For Android run: npm run test:e2e:android:local gutenberg-editor-unsupported-blocks.test

Expected behavior
The unsupported block UI test should succeed.
