Create a leoDocs.leojs and redo the documentation in markdown into a website

[boltex]

Thanks to Inspired Mars for this suggestion: Implement most of https://groups.google.com/g/leo-editor/c/FOAqUEHcHSY (except the name change!)

• Create a leoDocs.leojs and redo the documentation in markdown into a website to be hosted at https://felixworkshop.com/leojs.
• Use docusaurus for now, make something that works and change the leonine structure or website engine later. (leovue, sphinx, or other...)
