Allow feedback form to be submitted without feedback text

[lexi-taylor]

Description

Feedback form needs to be submitted in the expected format even when no feedback text is provided (still record like or dislike):
{ "type": "invoke", "name": "message/submitAction", "value": { "actionName": "feedback", "actionValue": { "reaction": "like", "feedback": { "feedbackText": "" } } } }

Design

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation

Changes:

• Replaced the deprecated hasFeedbackLoop with isRequireReviewAction
  • The hasFeedbackLoop is designed for patching service and it should not be called outside of patching, thus, it is marked as deprecated
• Moved the test from /fluent/ to /feedbackForm/
  • /fluent/ is for things that is specific to Fluent, such as layout or specialized behaviors. This "empty feedback" feature is not specific to Fluent
• Fixed a test which part of the steps were skipped
• Added deprecation notes to helper functions marked as deprecated, they are for patching the service
