Description

In the past, somebody had used VisualStudioCode to edit files with the bad lucky that this project doesn't have config compatible with fpb-lint. Thus, extra modifications are made when edit or commit files.

Moreover, people use to have installed markdownlint or markdown all-in-one addons to speed up somethings like TOC index or other stuff

Why is this valuable (or not)?

This PR adds the config necessary to minimize this kind of issues again. The config is parametrized (there where could be applied) according to remark config selected to free-programming-books-lint project
