Create separate pages for all the docs and info

[vbuberen]

⚠️ Is your feature request related to a problem? Please describe

Currently there is some inconsistency in having README in develop branch.
In case of adding some feature and its description into develop users see this description and think that this feature is available in the latest stable release, while it might be not released yet. Such situation happened recently.
Also, Chucker already has quite an extensive amount of info which should be hosted somewhere.

💡 Describe the solution you'd like

Have some separate pages like Github pages or something like https://squidfunk.github.io/mkdocs-material/ (much better solution) and have all the info, docs (including KDocs), recipes and whatever might be useful for library users updated separately to not be influenced by updates in develop branch, so the info is always correct for the latest stable version.

🙋 Do you want to develop this feature yourself?

It is more yes than no when I deal with other things I promised to do in other Issues.

• Yes
• No
