Fix all persistently broken URLs (#736)

There are some schools which use broken technology to run their sites, which
set session cookies and session IDs before anything can work. This fails with
the link checker, that just hits a redirect loop, so we need to skip these sites

Update URLs when new ones could be found, disable others where
the websites have just gone away

 ## Description
 
 Visualising HEP event data is currently typically done per experiment (e.g. [VP1](http://atlas-vp1.web.cern.ch/atlas-vp1/home/), [Iguana](https://doi.org/10.1016/j.nima.2004.07.036), [Fireworks](https://iopscience.iop.org/article/10.1088/1742-6596/219/3/032014/pdf)), and normally involves the installation of dedicated software. However modern browsers are more than capable of showing complex detector geometry, as well as representations of the underlying physics. As the [Visualisation](https://arxiv.org/abs/1811.10309) section of HSF Community White Paper explained, using an intermediate data format (e.g. JSON) makes it possible to separate the event display from the underlying (experiment-specific) software framework. 
 
-[Phoenix](https://hepsoftwarefoundation.org/phoenix/) is a framework that can be used by any typical (e.g. colliding beam) High Energy Physics experiment. It was initially based on work done for the TrackML [Kaggle](https://www.kaggle.com/c/trackml-particle-identification)/[Codalab](https://competitions.codalab.org/competitions/20112) challenges (and internal use by ATLAS). We were working with a GSOC student in 2019 who ported it to [angular](https://angular.io), and added new functionality (such as overlays, compound objects etc). A [LHCb example](http://hepsoftwarefoundation.org/phoenix/lhcb) has since been added, so the underlying principle is well validated, and various "loaders" exist to read JSON, Atlas JiveXML, LHCb and TrackML event data. The task now is to make it more user friendly, and to add more functionality.
