Improve confusable character string (#24911)

Very small UX change, "confusable" is a word that is indeed valid, but
when you look it up online, it doesn't take long for this adjective to
appear in [its technical Unicode-related
context](https://util.unicode.org/UnicodeJsps/confusables.jsp). I think
that it throws me off as a person that doesn't speak English natively.

I think that this could be replaced with "can be confused with". As the
change is very small and purely a matter of preference, if you (the
maintainer) believe that this shouldn't be included, feel free to close
this without any further discussion, as your time would probably be
better used elsewhere.
