fix(textarea): support pastes that end with a newline character

Browse Source 
My previous fix did not properly handle a multi-rune input that *ends*
with a newline character. In that case, the final newline was removed.

I found this using the test suite I built for textarea in bubbline at
https://github.com/knz/bubbline/tree/main/editline/internal/textarea/testdata.
