feat: replace trailing whitespace with a newline

[justinmayhew]

This replaces some trailing whitespace with a newline, making Git happy. :-)

Here's a diff showing the current (probably undesired) behaviour on the last two lines:

diff --git a/path/tsconfig.json b/path/tsconfig.json
index f4d712c..a8fae12 100644
--- a/path/tsconfig.json
+++ b/path/tsconfig.json

   ]
 }

\ No newline at end of file

Thanks for the awesome tool!
