Sphinx link check fix

[daschuer]

This fixes some links and put the rest to linkcheck_ignore. This way we get rid of the permanent failing CI.
The pre-commit failure is fixed here: #482

[Swiftb0y]

Can you rebase now that #482 has been merged?

[daschuer]

Done

Thank you. We should documents somewhere that authors need to fixup anchors on github wikis.

Thank you. We should documents somewhere that authors need to fixup anchors on github wikis.

Or even better, we could make a little script that auto-replaces the anchors and add that as a pre-commit hook.

For reference, I documented the Shell commands i used for bulk replacing the anchors in the commit message back then (see 71916cd), but I suppose Python script would be preferable so that it also works for Windows users.

I agree, but I didn't want the scope of this PR to grow ten-fold.

[Holzhaus]

Ah, I took your comment as a general recommendation, not a request to add documentation as part of this PR.

[Swiftb0y]

I went ahead and implemented the auto-fixup myself. I've never implemented a pre-commit hook, also my python is a bit dusty. I'd appreciate a thorough review. daschuer#4

The script is merged. Thank you @Swiftb0y.
Can we merge this now?

[Swiftb0y]

LGTM. Whats our policy on merging PRs from multiple authors? Parts of this PR are technically mine so am I still allowed to merge? Does somebody else want to hit the button?

[daschuer]

You part has been reviewed by me and Jan, so I think the second pair of eyes rules is fulfilled if you just press merge.
