Track and fix dead links (meta)

Sure, how do you think we should do it?

[rzr]

With a crawler ?

Using https://www.drlinkcheck.com

I was able to identify:

404 Not found | https://www.openfaas.com/community/OutboundLinked from: https://docs.openfaas.com/community/

This HTML url

I guess a rewrite is missing somewhere ?

The site gave 6 404s, but as far as I can see, they aren't broken. Feel free to check them out and send PRs if you can see broken ones.
