Invalid Link to Course about cookbook

[kelvins]

There is a Github action that can be used to check for broken links:

@kelvins I have decided to test out https://github.com/lycheeverse/lychee-action, seems ok so far, I coupled it with the issue creation out of the report (#116) - pleas do comment if you think this is a way to go, since I haven't directly used them before. If you agree the lychee-action will do the job in helping to identify the broken links on a once a week basis, I will close this issue. 👍 or 👎? 😃

@kelvins thanks for linking me to this checker, I will test it asap. It seems to have more stars than the one I stumbled upon, which was https://github.com/lycheeverse/lychee-action
