Fix broken links on the website

This MR fixes some broken links on the website.

A link is still broken: https://gforge.inria.fr/projects/gtg/, but I don't know the new URL (has it been migrated ?).

I don't think we created a new repository for GTG appart from the version integrated into EZTrace. Maybe we should extract the lib and set it as a submodule in EZTrace.

@trahay is there another repository for it ? should we create it or not ?

@faverge GTG was not migrated before gforge end of life, so there's no repository for it. The upcoming version of EZTrace will no longer use GTG, so I don't have the need for a GTG repository, but it can still be usefull to have it somewhere. I'll create a github repo for GTG and move it there. We'll miss the commit history though :(

Well it seems that I already moved GTG to github in 2020 and I forgot it :D Here's the repo URL: https://github.com/trahay/Generic-Trace-Generator
