Enhance labeling workflow

[SlyCaptainFlint]

Summary:

This PR does two things:

1. Improves the labeling workflow in cases where the user is on a supported version but a higher patch number is available. Now, the label name will be friendlier ('Newer Patch Available') and we will report the version they should consider upgrading to in the message body. Once this change is merged, I can also rename all existing versions of this label for consistency.
2. Moves the addDescriptiveLabels.js script to the workflow-scripts folder for consistency with the other workflow scripts.
