Issue: Honour file ending rules in data files

[davidsneighbour]

Editing a data file via frontMatter.data.files and Dashboard > Data results in the saved/changed file being saved without "newline at the end of the file". My linting rules expect a newline, so my linting always results in an extra step to add a new line.

Would it be possible to somehow check the file before changing it and using the existing characters after the json is closed (] or }) somehow? Or maybe add a config variable that enables newline/no-newline for edited files?

@davidsneighbour instead of checking the file, I'll use the files.insertFinalNewLine setting from VS Code.
