Subject: [PATCH] Fix: Fix blank lines being added at the end of the markdown
 file for each image on the page

Each image reference is renamed by reading the markdown file and writing it back with `Set-ContentNoBom`, which appends a newline. So a page with e.g. 27 images (pen/hand written drawings are exported as one image per stroke) ended with 27 blank lines.

Now trailing blank lines are removed before writing the final markdown file, which still ends with a single newline.
