Add github workflow to check links and open issues reporting them

[micalevisk]

My first attempt on use https://github.com/lycheeverse/lychee-action to automatically create an issue reporting all bad links. Here's an example of that issue: https://github.com/micalevisk/coding-interview-university/issues/1 This issue will be created only if there's some bad link on README.md file or in any .md on translations dir

Besides that, this workflow will find the last open issue with the label 'report' and update it instead of creating a new one. Or will close it if there's no bad link found.

Not sure if you guys are looking for something like this, tho.

Pretty cool. It looks like it needs to be slowed down a bit, it's getting throttled and causing 429s.

[jwasham]

Thanks Micael. Has the throttling issue been fixed?

[micalevisk]

I didn't face this issue in my tests with GH Actions, tbh. Also, I don't believe we can do something as a users of lychee tool :/

Looks like they didn't fixed it yet: lycheeverse/lychee#367

actually, I think we could use --max-concurrency (maximum number of concurrent network requests) option to circunvemt this, but I don't know which value will be good. The default is 128

Because this is hitting a lot of the same domains, try setting it to 5. It doesn't need to be fast, so if there's a delay of a minute or so before a PR comes in, that's ok.

[micalevisk]

this workflow was intended to run on a scheduled basis (once in a month) or manually. Do you think another one for open PRs is worth it? I'll need to figure out how can I run the checks only in the links added in the PR then (actually I'm already look into this because I need this feat in another project)

[jwasham]

Nope, you're right. i don't know why I was thinking that. Once a month is fine.

Thank you! Looking forward to the results!
