Move documentation to separate doc website

[strdr4605]

Abstract

As I see that documentation of this library is quite big. Maybe is a good idea to move it to a static website?!

I suggest https://v2.docusaurus.io/ as I used it for 2 projects and was pretty happy!

Other options:

• https://www.gitbook.com/
• https://docsify.js.org/
• https://grazedocs.io/
• https://www.mkdocs.org/
• https://couscous.io/

Implementation details

Doc generator may be located in documentation folder.
Using actions-gh-pages docs will be published at https://maximbircu.github.io/devtools-library
