Broken link remains to http://demo.requs.org/ on requs site

[avidrucker]

I suggest the link be removed if there is no plan to revive the demo. See issue #109 for context

@yegor256 May I remove the link from https://github.com/yegor256/requs/blob/462a6539ee4cad7775572014927322645ad50536/jekyll/index.md?plain=1#L18 ? At this moment, heroku free plan hosting is dead.

@nikzor it's better to put the project back online to Heroku

@yegor256 https://www.heroku.com/pricing In this case we need to switch to another free service, because Heroku pricing doesn't provide free option Temporarily, the link may be removed from the readme, or a comment, that it doesn't work now may be added
