Update form-field-label-descriptive-cc0f0a.md

[colabottles]

Based on feedback from ACT Task Force, we are not sure about the update to the applicability and the expectation and we are looking for feedback.

Need for Call for Review: This will require a 1 week Call for Review << small changes affecting a small number of test cases, if in doubt do not use this.

• [ ] Add label to indicate if it's a Rule, Definition or Chore.
• [ ] Link the PR to any issue it solves. This will be done automatically by referencing the issue at the top of this comment in the indicated place.

How to Review And Approve

• Go to the “Files changed” tab
• Here you will have the option to leave comments on different lines.
• Once the review is completed, find the “Review changes” button in the top right, select “Approve” (if you are really confident in the rule) or "Request changes" and click “Submit review”.
• Make sure to also review the proposed Call for Review period. In case of disagreement, the longer period wins.
