use different article because spray.io is dead

See #541

I'm not sure if https://www.baeldung.com/scala/magnet-pattern is ideal so if anyone has a better suggestion, pass it on.

This is a copy of the original blog.

Would it make sense for us to copy this into the Pekko HTTP docs?

@sirthias would you have any objections if we did this?

@mdedetrich @raboof @jrudolph @kerr @nvollmar @Roiocam any thoughts?

Is there an issue with using the original spray link but via wayback machine? I believe this is standard practice for such style references?

[pjfanning]

I can see that using the Wayback link is ok in the short term but it does lead to users being asked for donations, etc.

Seems like the least worst option to me, especially since the whole point of Wayback machine is to archive this content forever?

As the spray is there, I think this is fine, user would like to see the content, not the url

LGTM

I'm sorry that spray.io is dead now, but I was personally sitting on the domain and hosting cost for >10 years before eventually getting an offer for the domain from a nice someone from Korea who would like to use it for another not-for-profit project.
So I sold and transferred it two days ago.

Part of the deal is the keep the old artifact repo at http://repo.spray.io (which still sees a decent amount of traffic!) intact for some time longer, so that's not a problem.

The only thing of some value on the actual spray.io site was probably the post on the magnet pattern (from 2012!).
I'm completely fine with linking to the archive version of it, if that works for pekko.

An alternative could be to directly implant it into the pekko docs. The source is still around and written in reStructuredText (my preferred format at the time), which shouldn't be too hard to transcribe to Markdown or similar.

Thanks @sirthias for the quick and detailed response.

GitHub does a pretty decent job of rendering the .rst file too - so linking to that may be an option.

I'm happy enough to use Wayback Machine link as this PR now does.
