Registration form adding questions

## Context

- The "Question" input field has a value of 'Question' inputted in by default when it should be empty
- When deleting the default 'Question' value inputted, the placeholder is shown (placeholder shown in second image)
- When users type into the field, it adds to 'Question' say they press 'd' then it becomes 'Questiond'

## Requirements

- Make it like other input fields and have the default value not be "Question" but rather blank

## Acceptance Criteria

- [ ] Fulfill the above requirements

Start at the registration form entry point and reproduce the Question field behavior shown in the issue. The field is done when it starts blank, displays its placeholder when empty, and user input no longer retains or appends to a default “Question” value.
