feat: Add all option to indicate typos (@Leonabcd123)

[Leonabcd123]

Description

Added an "all" option to indicate typos that both keeps the replace functionality, and makes the below functionality show the correct instead of the incorrect letters. We just check whether the mode is all before 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 all OR replace/below.

I'm not so sure whether we need to change the if statement at the start of updateHintsPosition to:

if (
    ActivePage.get() !== "test" ||
    TestState.resultVisible ||
    (Config.indicateTypos !== "below" && Config.indicateTypos !== "all")
  )

It works fine for me without it, but I would still like to get feedback on this.
