Allow danger variant to be disabled

[ojeytonwilliams]

freeCodeCamp/freeCodeCamp#55724 makes the danger button disabled until the user has entered the expected text.

@huyenltnguyen I know this was intentional, but now we have some tension: we can only get the client to pass type-checking if we use ts-ignore/ts-expect-error, which isn't ideal. Given the use-case in the linked PR, can we allow the danger variant to be disabled or does the client need to do something differently?
