React Editor review criteria comment required

The Review Criteria settings have a Comment Required boolean value.
In the React Edtior, we need to implement the Rejection Modal to reflect this value for each criteria.
If a criteria with the comment required value is selected, then the Reject Translation button should be disabled until a comment has been entered.

A 'Unspecified Criteria' option should also be added to the dropdown, which will require a comment by default.
The Reject Translation button will be disabled until a criteria has been selected and its 'comment required' condition also met.
