refactor(mantine): migrate nlp qa number input DEV-1163 (#6373)

### 💭 Notes
`NumberInput` from mantine returns a number, but the logic of the
response form requires a string. Instead of doing too much work I just
converted the mantine return to a string

### 👀 Preview steps

1. ℹ️ have an account and a project with submissions to open nlp
2. create a "Number" analysis question 
5. 🟢 [on PR] notice that the functionality remains the same
