Preserve trailing newline

[jloh]

First off, thanks for creating this! Obsidian just continues to become more and more powerful thanks to plugin creators like yourself.

Secondly, it'd be amazing if this plugin could handle retaining a newline in a section when adding to the bottom.

My use case is my daily notes have a TODO section/format like this:

# {{date:dddd Do MMMM YYYY}}

## TODOs

## Notes

So I have a newline under TODOs to separate it and the ## Notes section. When I insert new TODO items I add them to the bottom of a tickbox list like this:

# {{date:dddd Do MMMM YYYY}}

## TODOs
- [ ] Todo item one
- [ ] todo item two added after the above but keeping the trailing newline

## Notes

I can insert new items at the beginning of the section using -H 'Content-Insertion-Position: beginning' which works great but I'd like to insert them at the bottom and using -H 'Content-Insertion-Position: end' inserts them below the trailing newline.

It'd be great if I could keep the trailing newline so new PATCH requests result in my example above. Hopefully this makes sense!
