refactor: add editorconfig rules for md-files

[JanKru]

Summary

If you set trim_trailing_whitespace = true, it will no longer be possible to start a new line with two blank lines in the markdown files.

Basic example

Try it in example.md. I used vs code with editorconfig plugin.

Motivation

Would be nice to have new lines. Added specific rules for md @h-enk .

[..], it will no longer be possible to start a new line with two blank lines in the markdown files.

Why would you want that (is one blank line not enough) /what's the use case?

[JanKru]

Thanks for the reply :)

One example, if I write on a markdown-file without 2 spaces after the end of First line line

#markdown
First line
Second line

# rendered
First line Second line

---

# markdowm
First line

Second line

# rendered
First line

Second line

---

So if I want to have

# rendered
First line 
Second line

as outcome I must write it as

#markdown
First line   
Second line

with two spaces after First line
which is not possible with current editorConfig?
