Hi everyone, I have an idea to expand the current README documentation to include a detailed section on how to debug individual Magento 2 cron jobs, rather than just the default cron group.

While we currently have instructions on debugging the default cron group (it works only with the default cron group, honestly I don't know the reason), I recently discovered a way to debug individual cron jobs separately.

This approach could provide developers with more precise control during the debugging process, running only one cronjob, not the entire cron group.

Before I proceed with writing the detailed documentation for this, @markshust I wanted to ask if this would be useful. If so, I can include step-by-step instructions on how to configure PhpStorm and Xdebug to target specific cron jobs, which could improve troubleshooting and efficiency.

Thanks @YevhenZvieriev, I absolutely love this contribution!

However, the current README is a mess. It's super long and getting hard to read. I'd like to overhaul it with something like GitHub Pages (ex. https://gibinfrancis.medium.com/creating-structured-multi-page-documentation-with-github-pages-794b100a4941).

If ok, I'll sit on this PR for a bit until the docs are overhauled, but will gladly take stuff like this in, as I think it would make a great contribution to the repo. I think even a new "how to" section where we can place stuff like this in would be an awesome idea.

@Nolwennig very cool -- I wish it did multiple pages!
