Joshua and Jesus are the same name. In fact, if we don’t see that, we miss the typology meant to be seen when Gabriel tells Mary to name him Jesus/Joshua. We tend to be so arrogant with our English language
We are in the golden age of translations! Today we are able to be more accurate to the original autographs than ever before! Praise God, for he has allowed us to discover many thousands more of the oldest found fragments in just the past few decades. And further, praise God that these oldest fragments and manuscripts prove that the translations we’ve had throughout the centuries have been accurate and faithful. Even when there were a few things added at times, either by scribes or others (John 5:4, etc.), it didn’t affect the central meaning of the text nor the truth of the gospel.
