the structure of the website repo is a mess and confuses with the syntax repo

[amtoine]

currently, the content of this website is split into two parts:

• https://oberonproject.github.io/ uses ./index.html, ./styles.css and ./res/ and mainly redirects to external links and the syntax
• https://oberonproject.github.io/syntax uses the page files in ./syntax/

the former are directly written in this repository the latter are generated with the generate-language script over on the syntax repo the page files go in ./website/ and then have to be moved to this repo manually...

some ideas

• move the generation script over from the syntax repo to here, making the syntax repo dedicated to the syntax itself
• use the main branch for scripts and resources
• put the real pages and HTML files on a new gh-pages branch
• deploy the gh-pages branch onto https://github.com/oberonproject
