Resolve latest linkcheck issues

[phillxnet]

During a more recent docs build we have some link maintenance to attend to, see PR #472 .

This issue is proposed to address these requirements.

[phillxnet]

We have recently removed our Owncloud Rock-on due to upstream image archived status:

• Issue: "The image for Owncloud is no longer maintained": https://github.com/rockstor/rockon-registry/issues/357
• PR: "Remove OwnCloud Rockon - archived development": https://github.com/rockstor/rockon-registry/pull/359

So we can similarly remove the howto and any associated link in docs as there is one broken and a few redirects associated with this issue.

[phillxnet]

Noting additional removals/updates regarding some of our redirect issues:

• Remove Crashplan Rockon: https://github.com/rockstor/rockon-registry/pull/374

Also noting some redirects are for multiple language sites. Leaving these where I've noticed as they pick-up on the browser lang setting.

Second pass:

First in above replaced with GitHub as site non-existent. Second in above sutdown now: https://www.diyaudio.com/community/threads/mysqueezebox-com-shutting-down.408366/ Removing for now and we have the following issue opened: https://github.com/rockstor/rockon-registry/issues/375 Replacing Mindcraft.net with wikipedia page as it regularly false flags: likely due to it rejecting robot connections such we use in this test.
