fix: import sorting with interpreter command

[vladislavarsenev]

Hi,

This tiny fix aimed to close case with combination of ignore comment and interpreter directive. Interpreter directive has to be on the first line, thus in this case comment with ignoring would be on 2nd line instead of the 1st.

like this

#!/usr/bin/env node
// sort-imports-ignore

Also, I put .DS_Store file to gitignore. It's a common utility file within Mac OS. It creates it in every directory.
