"needs reply to review" label process is broken

[petersmythe]

Hi @ewpatton @halatmit etc

Please refer to my PR #3160 (comment) as well as the instructions copied below from https://docs.google.com/document/d/1sAw0QObTxTWqRX7GQRCa2z9TIV2r5AKT9UKMFF1acZI/pub#h.ibcvzqybkfp8 (linked directly from https://mit-cml.github.io/appinventor-sources/)

When you add the pull request add are ready for it to be reviewed, add the label “status: needs review” to the pull request. Later, during the review process, the reviewer might change that to “needs reply to review”. After you address the review comments, change the label back to “needs review”. There might be several back-and-forth cycles during the review.

You might not be aware that new contributors do not have the permissions to add or change labels:

so this process to indicate the back-and-forth status of the review cycle needs to be revised slightly, please.

Peter
