feat(test): add indicate typos both (@Leonabcd123) (#7072)

### Description

Added a "both" option to indicate typos that keeps the replace
functionality, and makes the below functionality show the correct
instead of the incorrect letters. We just check whether the mode is
`both` when deciding whether to pass `input` to `createHintsHtml` or to
pass `currentWord`. All functionality of replace and below is kept by
just adding or operators to check whether indicateTypos is `both` OR
replace/below.

Implementing #7024
