[Bug] Error message incorrect on entering the name of a student into the affected cohort page

Overview
When a user navigates to the What is the name of one of the students from the affected cohort page and attempts to continue without adding a name an error message displays stating Enter the name of the student with an [request type].
As the title of the page refers to entering the name of one of the students and the error message refers to enter the name we have a mismatch.
The error message should read Enter the name of one of the students from the affected cohort.

Steps to reproduce

1. Navigate to DEV/QA and sign in.
2. Enter the 16 to 19 checking window and follow the pages through: Report and issue with an exam result > Incorrect grade or Missing qualification > Yes to the whole cohort > 2 or more for the number of students.
3. Click Continue on the What is the name of one of the students from the affected cohort? page.
4. Note that the error message reads Enter the name of the student [request type]

Expected result
The error message reads Enter the name of one of the students from the affected cohort.

Screenshots

Reproduce the flow in DEV or QA through the affected-cohort pages, then start from the validation for the “What is the name of one of the students from the affected cohort?” page. Update the empty-name error so it matches the page wording, and verify that clicking Continue without a name shows the expected message.
