Get ride of dead links on README.md file

[micalevisk]

Hey! I've use the link checker https://github.com/lycheeverse/lychee against your README.md, and found a few broken links:

btw do you think that could be cool to use their GitHub Action lychee-action to write GH workflows that will perform links checker against all Pull Requests, and every month, look up for broken links (404 or 401 responses in Lychee summary) and create automated issues to let you aware of they? I can prototype and test this in a fork and make a PR if you want 😄
