internal/lsp: fix formatting bug that keeps adding extra newlines

If a file ends with an empty newline, go/token treats the newline as the
final character of the previous line. VSCode, however, treats this as a
final line with no characters. We handle this by determining if the file
we are formatting ends with a newline character and updating the
protocol ranges accordingly.
