And - this happens all the time, you can look at Enid Blyton and things like Biggles for properties that have quietly changed language here and there to keep them from getting too dated. Panties get bunched when the currency changes from pounds and shillings, the _Spectator_ trots out another piece about wokeity sending us all to hell because Noddy and Big Ears aren’t gay any more - but those books stay in print.
If Mark Twain is more to your taste, go have a browse of an early 20th centry edition and see how you feel about teaching the language in that to your kids.
