Description of the pull request

The sample code in Step 5 of the tutorial throws a TypeError: Cannot read property 'binary' of undefined when attempting to execute the applyImage command. This PR updates the parameters in the tutorial per the linked source code:

await tempFile.write(photoObj, { format: uxp.storage.formats.binary });

I think this might help explain the happy coincidence scenario over in https://forums.adobexdplatform.com/t/uxp-is-not-defined/1575/4 as well?
