Title: Renamed the CONTRIBUTING file to CONTRIBUTING.md

Renamed the file so that GitHub effectively uses the Markdown syntax already present in the file when presenting it.
It will make it more readable.

There is no issue related to this PR.
Please include [ci skip] since this affects only the documentation.
