make pages more easily editable #43
Description
It was rather straightforward to contribute to the wiki, editing pages of the 'howto' section directly from the browser though a link available on the wiki page itself, making is easy to fix typos or propose improvements to existing content.
After migrating away from github wiki, this feature has been lost.
Materials mkdocs has such an option : https://squidfunk.github.io/mkdocs-material/setup/adding-a-git-repository/?h=edit+uri#code-actions
The main problem here is that some pages are generated from gpac's source code ( gpac -genmd ).
