List of dead links

[B-Mahdj]

Hi,
After writing a PR to fix dead link (#840) I tried to find a tool that could automate the finding of dead links and found out about Lychee, a link checker written in Rust.

I've ran the CLI on local and here are the results of the links that are broken :

This tool is not perfect because of how the pathing is handled in this project, so for example the broken link I've found here (#840) cannot be found using this tool but it gives the broken external links at least.
